2003-07-29Apply (a somewhat revised version of) Greg Mullane's patch to eliminateTom Lane
heuristic determination of day vs month in date/time input. Add the ability to specify that input is interpreted as yy-mm-dd order (which formerly worked, but only for yy greater than 31). DateStyle's input component now has the preferred spellings DMY, MDY, or YMD; the older keywords European and US are now aliases for the first two of these. Per recent discussions on pgsql-general.
2003-07-28A visit from the message-style police ...Tom Lane
2003-07-20Another round of error message editing, covering backend/commands/.Tom Lane
2003-07-17Make EXTRACT(TIMEZONE) and SET/SHOW TIMEZONE follow the SQL conventionTom Lane
for the sign of timezone offsets, ie, positive is east from UTC. These were previously out of step with other operations that accept or show timezones, such as I/O of timestamptz values.
2003-07-15Now that I look, SHOW TRANSACTION_ISOLATION isn't quite consistentTom Lane
with SET TRANSACTION_ISOLATION, either.
2003-07-15Cause SHOW DATESTYLE to produce a string that will be accepted by SETTom Lane
DATESTYLE, for instance 'SQL, European' instead of 'SQL with European conventions'. Per gripe a month or two back from Barry Lind.
2003-06-27Add is_superuser parameter reporting, soon to be used by psql.Tom Lane
2003-06-06Add defense in assign_session_authorization() against trying to doTom Lane
catalog lookups when not in a transaction. This prevents bizarre failures if someone tries to set a value for session_authorization in postgresql.conf. Per report from Fernando Nasser.
2003-05-22Add defense against possibility that tzname[] doesn't exist.Tom Lane
2003-05-18Add code to test for unknown timezone names (following some ideas fromTom Lane
Ross Reedstrom, a couple months back) and to detect timezones that are using leap-second timekeeping. The unknown-zone-name test is pretty heuristic and ugly, but it seems better than the old behavior of just switching to GMT given a bad name. Also make DecodePosixTimezone() a tad more robust.
2003-04-27Clean up some problems in SetClientEncoding: failed to honor doit flagTom Lane
in all cases, leaked TopMemoryContext memory in others. Make the interaction between SetClientEncoding and InitializeClientEncoding cleaner and better documented. I suspect these changes should be back-patched into 7.3, but will wait on Tatsuo's verification.
2003-04-25In the continuing saga of FE/BE protocol revisions, add reporting ofTom Lane
initial values and runtime changes in selected parameters. This gets rid of the need for an initial 'select pg_client_encoding()' query in libpq, bringing us back to one message transmitted in each direction for a standard connection startup. To allow server version to be sent using the same GUC mechanism that handles other parameters, invent the concept of a never-settable GUC parameter: you can 'show server_version' but it's not settable by any GUC input source. Create 'lc_collate' and 'lc_ctype' never-settable parameters so that people can find out these settings without need for pg_controldata. (These side ideas were all discussed some time ago in pgsql-hackers, but not yet implemented.)
2003-02-01Fix assign_session_authorization() to not be confused by all-numericTom Lane
user names. Per recent reports.
2002-12-05More cleanup of userid to be AclId rather than Oid.Bruce Momjian

2002-07-18I have committed many support files for CREATE CONVERSION. DefaultTatsuo Ishii
conversion procs and conversions are added in initdb. Currently supported conversions are: UTF-8(UNICODE) <--> SQL_ASCII, ISO-8859-1 to 16, EUC_JP, EUC_KR, EUC_CN, EUC_TW, SJIS, BIG5, GBK, GB18030, UHC, JOHAB, TCVN EUC_JP <--> SJIS EUC_TW <--> BIG5 MULE_INTERNAL <--> EUC_JP, SJIS, EUC_TW, BIG5 Note that initial contents of pg_conversion system catalog are created in the initdb process. So doing initdb required is ideal, it's possible to add them to your databases by hand, however. To accomplish this: psql -f your_postgresql_install_path/share/conversion_create.sql your_database So I did not bump up the version in cataversion.h. TODO: Add more conversion procs Add [CASCADE|RESTRICT] to DROP CONVERSION Add tuples to pg_depend Add regression tests Write docs Add SQL99 CONVERT command? -- Tatsuo Ishii

2002-05-17Merge the last few variable.c configuration variables into the genericTom Lane
GUC support. It's now possible to set datestyle, timezone, and client_encoding from postgresql.conf and per-database or per-user settings. Also, implement rollback of SET commands that occur in a transaction that later fails. Create a SET LOCAL var = value syntax that sets the variable only for the duration of the current transaction. All per previous discussions in pghackers.
2002-05-06Accept SET SESSION AUTHORIZATION DEFAULT and RESET SESSION AUTHORIZATIONTom Lane
to reset session userid to the originally-authenticated name. Also, relax SET SESSION AUTHORIZATION to allow specifying one's own username even if one is not superuser, so as to avoid unnecessary error messages when loading a pg_dump file that uses this command. Per discussion from several months ago.
2002-04-22Convert GUC parameters back to strings if input as integers.Thomas G. Lockhart
Change elog(ERROR) messages to say that a variable takes one parameter, rather than saying that it does not take multiple parameters.
2002-04-22Check for multiple arguments on parameters which do not allow them.Thomas G. Lockhart
The last version caught this with an assert because I wasn't sure whether we should elog(ERROR) or just loop through the parameters.
2002-04-21Initialize or set a couple of variables to suppress compiler warnings.Thomas G. Lockhart
These were for cases protected by elog(ERROR) exits, but may as well keep the compiler happy. Not sure why they don't show up on my gcc-2.96.x version of the compiler.
2002-04-21Allow more choices for style of value in various SET commands. Formerly,Thomas G. Lockhart
most required a stringy syntax in the parser; now integers and floats can (or should) be handled. There is at least one cheesy error message mentioning sending mail to me if there are problems; should be changed prior to release. Allow lists of values from the parser in more cases. If multiple arguments were not allowed previously, they probably are not allowed now, but at least the data structures being passed around are more consistant across more cases.
2002-03-29pg_type has a typnamespace column; system now supports creating typesTom Lane
in different namespaces. Also, cleanup work on relation namespace support: drop, alter, rename commands work for tables in non-default namespaces.
2002-03-06Change made to elog:Bruce Momjian
o Change all current CVS messages of NOTICE to WARNING. We were going to do this just before 7.3 beta but it has to be done now, as you will see below. o Change current INFO messages that should be controlled by client_min_messages to NOTICE. o Force remaining INFO messages, like from EXPLAIN, VACUUM VERBOSE, etc. to always go to the client. o Remove INFO from the client_min_messages options and add NOTICE. Seems we do need three non-ERROR elog levels to handle the various behaviors we need for these messages. Regression passed.
2002-03-02Commit to match discussed elog() changes. Only update is that LOG isBruce Momjian
now just below FATAL in server_min_messages. Added more text to highlight ordering difference between it and client_min_messages. --------------------------------------------------------------------------- REALLYFATAL => PANIC STOP => PANIC New INFO level the prints to client by default New LOG level the prints to server log by default Cause VACUUM information to print only to the client NOTICE => INFO where purely information messages are sent DEBUG => LOG for purely server status messages DEBUG removed, kept as backward compatible DEBUG5, DEBUG4, DEBUG3, DEBUG2, DEBUG1 added DebugLvl removed in favor of new DEBUG[1-5] symbols New server_min_messages GUC parameter with values: DEBUG[5-1], INFO, NOTICE, ERROR, LOG, FATAL, PANIC New client_min_messages GUC parameter with values: DEBUG[5-1], LOG, INFO, NOTICE, ERROR, FATAL, PANIC Server startup now logged with LOG instead of DEBUG Remove debug_level GUC parameter elog() numbers now start at 10 Add test to print error message if older elog() values are passed to elog() Bootstrap mode now has a -d that requires an argument, like postmaster
2002-02-23Save source of GUC settings, allowing different sources to be processed inPeter Eisentraut
any order without affecting results.
2001-12-09Honor the typmod field for time zone intervals.Thomas G. Lockhart
2001-11-21Allow 'PostgreSQL' as a date/time formatting style. Formerly, recognizedThomas G. Lockhart
'Postgres' only, but now accepts both.
2001-10-25pgindent run on all C files. Java run to follow. initdb/regressionBruce Momjian
tests pass.
2001-10-18Accept an INTERVAL argument for SET TIME ZONE per SQL99.Thomas G. Lockhart
Modified the parser and the SET handlers to use full Node structures rather than simply a character string argument. Implement INTERVAL() YEAR TO MONTH (etc) syntax per SQL99. Does not yet accept the goofy string format that goes along with, but this should be fairly straight forward to fix now as a bug or later as a feature. Implement precision for the INTERVAL() type. Use the typmod mechanism for both of INTERVAL features. Fix the INTERVAL syntax in the parser: opt_interval was in the wrong place. INTERVAL is now a reserved word, otherwise we get reduce/reduce errors. Implement an explicit date_part() function for TIMETZ. Should fix coersion problem with INTERVAL reported by Peter E. Fix up some error messages for date/time types. Use all caps for type names within message. Fix recently introduced side-effect bug disabling 'epoch' as a recognized field for date_part() etc. Reported by Peter E. (??) Bump catalog version number. Rename "microseconds" current transaction time field from ...Msec to ...Usec. Duh! date/time regression tests updated for reference platform, but a few changes will be necessary for others.
2001-09-19Avoid unnecessary strcasecmp -- replace by strcmp. Fixes reported bugPeter Eisentraut
that made setting serializable isolation level impossible in Turkish locale.

I found new bug in command/variable.c in parse_client_encoding(), nobody probably never see this error: if (pg_set_client_encoding(encoding)) { elog(ERROR, "Conversion between %s and %s is not supported", value, GetDatabaseEncodingName()); } because pg_set_client_encoding() returns -1 for error and 0 as true. It's fixed too. IMHO it can be apply.

2001-06-30Allow default transaction isolation level (a.k.a. set sessionPeter Eisentraut
characteristics) to be set through GUC.
2001-06-12Extend GUC concepts of parse_hook and assign_hook to all four supportedTom Lane
datatypes, not only strings. parse_hook is useless for bool, I suppose, but it seems possibly useful for int and double to apply variable-specific constraints that are more complex than simple range limits. assign_hook is definitely useful for all datatypes --- we need it right now for bool to support date cache reset when changing Australian timezone rule setting. Also, clean up some residual problems with the reset all/show all patch, including memory leaks and mistaken reset of PostPortNumber. It seems best that RESET ALL not touch variables that don't have SUSET or USERSET context.

2001-01-24Change Copyright from PostgreSQL, Inc to PostgreSQL Global Development Group.Bruce Momjian
2000-12-03Ensure that all uses of <ctype.h> functions are applied to unsigned-charTom Lane
values, whether the local char type is signed or not. This is necessary for portability. Per discussion on pghackers around 9/16/00.
2000-10-26Fix breakage I introduced yesterday in MULTIBYTE compilations.Tom Lane
Sorry 'bout that, chief...
2000-10-25Support SET/SHOW/RESET client_encoding and server_encoding even whenTom Lane
MULTIBYTE support is not compiled (you just can't set them to anything but SQL_ASCII). This should reduce interoperability problems between MB-enabled clients and non-MB-enabled servers.
2000-09-22SetPGVariable() crashed on SET DateStyle TO DEFAULT and related cases.Tom Lane
2000-08-01Convert all remaining float4 and float8 functions to new fmgr style.Tom Lane
At this point I think it'd be possible to make float4 be pass-by-value without too much work --- and float8 too on machines where Datum is 8 bytes. Something to try when the mood strikes, anyway.
2000-07-14Implement SET SESSION CHARACTERISTICS and SET DefaultXactIsoLevel.Thomas G. Lockhart
2000-06-22Second pass over run-time configuration system. Adjust priorities on somePeter Eisentraut
option settings. Sort out SIGHUP vs BACKEND -- there is no total ordering here, so make explicit checks. Add comments explaining all of this. Removed permissions check on SHOW command. Add examine_subclass to the game, rename to SQL_inheritance to fit the official data model better. Adjust documentation. Standalone backend needs to reset all options before it starts. To facilitate that, have IsUnderPostmaster be set by the postmaster itself, don't wait for the magic -p switch. Also make sure that all environment variables and argv's survive init_ps_display(). Use strdup where necessary. Have initdb make configuration files (postgresql.conf, pg_hba.conf) mode 0600 -- having configuration files is no fun if you can't edit them.
