basically want your guys feedback. I have sprinkled some of my q's thru
the text delimited with the @@ symbol. It seems to work perfectly.
[ Removed @@ comments because patch was reviewed. ]
At the moment it does CHECK constraints only, with inheritance. However,
due to the problem mentioned before with the mismatching between inherited
constraints it may be wise to disable the inheritance feature for a while.
it is written in an extensible fashion to support future dropping of other
types of constraint, and is well documented.
Please send me your comments, check my use of locking, updating of
indices, use of ERROR and NOTICE, etc. and I will rework the patch based
on feedback until everyone
is happy with it...

from an empty text string. This makes them consistent with the de facto
behavior of type char's I/O conversion functions, and avoids generating
text values with embedded nulls, which confuse many text operators.

the same tuple slot that the raw tuple came from, because that slot has
the wrong tuple descriptor. Store it into its own slot with the correct
descriptor, instead. This repairs problems with SPI functions seeing
inappropriate tuple descriptors --- for example, plpgsql code failing to
cope with SELECT FOR UPDATE.

Python) to support shared extension modules, I have learned that Guido
prefers the style of the attached patch to solve the above problem.
I feel that this solution is particularly appropriate in this case
because the following:
PglargeType
PgType
PgQueryType
are already being handled in the way that I am proposing for PgSourceType.

it does not support 64bit integers. AFAIK that's the default data type for
OIDs, so I am not surprised that this does not work. Use gcc instead.
BTW., 7.1 does not compile as is with gcc either, I believed the
required patches made it into the 7.1.1 release but obviously I missed
the deadline.
Since the ports mailing list does not seem to be archived I have attached
a copy of the patch (for 7.1 and 7.1.1).
I've just performed a build of a Watcom compiled version and found a couple
of bugs in the watcom specific part of that patch. Please use the attached
version instead.

to do that, but inconsistently.) Make bit type reject too short input,
too, per SQL. Since it no longer zero pads, 'zpbit*' has been renamed to
'bit*' in the source, hence initdb.

the output of "egrep '^[0-9]' " is empty. Changing the pattern to
"egrep '^[ ]*[0-9]" generates the correct file.

things all into array.sql, to make things more manageable.

- New functions to create a portal using a prepared/saved
SPI plan or lookup an existing portal by name.
- Functions to fetch/move from/in portals. Results are placed
in the usual SPI_processed and SPI_tuptable, so the entire
set of utility functions can be used to gain attribute access.
- Prepared/saved SPI plans now use their own memory context
and SPI_freeplan(plan) can remove them.
- Tuple result sets (SPI_tuptable) now uses it's own memory
context and can be free'd by SPI_freetuptable(tuptab).
Enhancement of PL/pgSQL
- Uses generic named portals internally in FOR ... SELECT
loops to avoid running out of memory on huge result sets.
- Support for CURSOR and REFCURSOR syntax using the new SPI
functionality. Cursors used internally only need no explicit
transaction block. Refcursor variables can be used inside
of explicit transaction block to pass cursors between main
application and functions.

create_index_paths are not immediately discarded, but are available for
subsequent planner work. This allows avoiding redundant syscache lookups
in several places. Change interface to operator selectivity estimation
procedures to allow faster and more flexible estimation.
Initdb forced due to change of pg_proc entries for selectivity functions!

PageGetFreeSpace() was being called while not holding the buffer lock, which
not only could yield a garbage answer, but even if it's the right answer there
might be less space available after we reacquire the buffer lock.
Also repair potential deadlock introduced by my recent performance improvement
in RelationGetBufferForTuple(): it was possible for two heap_updates to try to
lock two buffers in opposite orders. The fix creates a global rule that
buffers of a single heap relation should be locked in decreasing block number
order. Currently, this only applies to heap_update; VACUUM can get away with
ignoring the rule since it holds exclusive lock on the whole relation anyway.
However, if we try to implement a VACUUM that can run in parallel with other
transactions, VACUUM will also have to obey the lock order rule.

type never scans a relation directly, it can't be an EPQ target.
Explicitly drop subplan's tuple table to ensure we have no buffer pin
leaks.

As a workaround 'vacuum analyze' could be used.

trees (mostly my fault). Repair. Also fix long-standing bug in ExecReplace:
after recomputing a concurrently updated tuple, we must recheck constraints.
Make EvalPlanQual leak memory with somewhat less enthusiasm than before,
although plugging leaks fully will require more changes than I care to risk
in a dot-release.
