-# Custom patch
-# Revision 1.9 2002/08/22 00:01:39 tgl
-# Add a bunch of pseudo-types to replace the behavior formerly associated
-# with OPAQUE, as per recent pghackers discussion. I still want to do some
-# more work on the 'cstring' pseudo-type, but I'm going to commit the bulk

-# Revision 1.12 2004/04/19 23:11:49 momjian
-# Update to my2pg 1.28, from:
-#
-# http://www.omnistarinc.com/~fonin/downloads.php#my2pg
-#
-# Revision 1.28 2002/11/30 12:03:48 fonin
-# PostgreSQL does not support indexes on the partial length of column,
-# e.g.
-# CREATE INDEX i_index ON table (column(16));
-# will not work. Fixed.
-#
-# Added command-line option -s that prevents my2pg from attempting convert
-# the data (currently only timestamps).
-#
-# Better timestamps conversion.
-#
-# Revision 1.27 2002/07/16 14:54:07 fonin
-# Bugfix - didn't quote the fields inside PRIMARY KEY with -d option.
-# Fix by Milan P. Stanic <[email protected]>.
-#
-# Revision 1.26 2002/07/14 10:30:27 fonin
-# Bugfix - MySQL keywords inside data (INSERT INTO sentence) were replaced
-# with Postgres keywords and therefore messed up the data.
-#
-# Revision 1.25 2002/07/05 09:20:25 fonin
-# - fixed data that contains two consecutive timestamps - thanks to
-# Ben Darnell <[email protected]>
-# - word 'default' was converted to upper case inside the data - fixed.
-# Thanks to Madsen Wikholm <[email protected]>
-#
-# Revision 1.24 2002/04/20 14:15:43 fonin
-# Patch by Felipe Nievinski <[email protected]>.
-# A table I was re-creating had a composite primary key, and I was using
-# the -d switch to maintain the table and column names
-# adding double quotes around them.
-#
-# The SQL code generated was something like this:
-#
-# CREATE TABLE "rinav" (
-# "UnidadeAtendimento" INT8 DEFAULT '0' NOT NULL,
-# "NumeroRinav" INT8 DEFAULT '0' NOT NULL,
-# -- ...
-# PRIMARY KEY ("UnidadeAtendimento"," NumeroRinav")
-# );
-#
-# Please note the space inside the second column name string in the PK
-# definition. Because of this PostgreSQL was not able to create the table.
-#
-# FIXED.
-#
-# Revision 1.23 2002/02/07 22:13:52 fonin
-# Bugfix by Hans-Juergen Schoenig <[email protected]>: additional space after
-# FLOAT8 is required.
-#
-# Revision 1.22 2001/12/06 19:32:20 fonin
-# Patch: On line 594 where you check for UNIQUE, I believe the regex should try
-# and match 'UNIQUE KEY'. Otherwise it outputs no unique indexes for the
-# postgres dump.
-# Thanks to Brad Hilton <[email protected]>
-#
-# Revision 1.21 2001/08/25 18:55:28 fonin
-# Incorporated changes from Yunliang Yu <[email protected]>:
-# - By default table & column names are not quoted; use the new
-# "-d" option if you want to,
-# - Use conditional substitutions to speed up and preserve
-# the data integrity.
-# Fixes by Max:
-# - timestamps conversion fix. Shouldn't break now matching binary data and
-# strings.
-#
-# Revision 1.21 2001/07/23 03:04:39 yu
-# Updates & fixes by Yunliang Yu <[email protected]>
-# . By default table & column names are not quoted; use the new
-# "-d" option if you want to,
-# . Use conditional substitutions to speed up and preserve
-# the data integrity.
-#
-# Revision 1.20 2001/07/05 12:45:05 fonin
-# Timestamp conversion enhancement from Joakim Lemstr�m <[email protected]>
-#
-# Revision 1.19 2001/05/07 19:36:38 fonin
-# Fixed a bug in quoting PRIMARY KEYs, KEYs and UNIQUE indexes with more than 2 columns. Thanks to Jeff Waugh <[email protected]>.

-# Revision 1.18 2001/03/06 22:25:40 fonin
-# Documentation up2dating.
-#
-# Revision 1.17 2001/03/04 13:01:50 fonin
-# Fixes to make work it right with MySQL 3.23 dumps. Tested on mysqldump 8.11.
-# Also, AUTO_INCREMENT->SERIAL fields no more have DEFAULT and NOT NULL
-# definitions.
-#
-# Revision 1.16 2001/02/02 08:15:34 fonin
-# Sequences should be created BEFORE creating any objects \nthat depends on it.
-#
-# Revision 1.15 2001/01/30 10:13:36 fonin
-# Re-released under BSD-like license.
-#
-# Revision 1.14 2000/12/18 20:55:13 fonin
-# Better -n implementation.
-#
-# Revision 1.13 2000/12/18 15:26:33 fonin
-# Added command-line options. -n forces *CHAR DEFAULT '' NOT NULL to be
-# converted to *CHAR NULL.
-# AUTO_INCREMENT fields converted not in SERIAL but in
-# INT* NOT NULL DEFAULT nextval('seqname').
-# Documentation refreshed.
-# Dump enclosed in single transaction from now.
-#
-# Revision 1.12 2000/12/14 20:57:15 fonin
-# Doublequotation bug fixed (in CREATE INDEX ON TABLE (field1,field2))
-#
-# Revision 1.10 2000/11/27 14:18:22 fonin
-# Fixed bug - occasionaly was broken CREATE SEQUENCE generation
-#
-# Revision 1.8 2000/11/24 15:24:16 fonin
-# TIMESTAMP fix: MySQL output YYYYMMDDmmhhss to YYYYMMDD mmhhss
-#
-# Revision 1.7 2000/11/22 23:04:41 fonin
-# TIMESTAMP field fix. Better doublequoting. Splitting output dump
-# into 2 transactions - create/load/indexing first, sequence setvals then.
-# Added POD documentation.

-=head1 NAME
-
-my2pg - MySQL -> PostgreSQL dump conversion utility.
-
-=head1 SYNTAX
-
- mysqldump db | ./my2pg.pl [-nds] > pgsqldump.sql
- vi libtypes.c
- make
- psql database < pgsqldump.txt
-where
-
-=over 4
-
-=item F<pgsqldump.sql>
-
-- file suitable for loading into PostgreSQL.
-
-=item F<libtypes.c>
-
-- C source for emulated MySQL types (ENUM, SET) generated by B<my2pg>
-
-=back
-
-=head1 OVERVIEW
-
-B<my2pg> utility attempts to convert MySQL database dump to Postgres's one.
-B<my2pg> performs such conversions:
-
-=over 4
-
-=item * Type conversion.
-
-It tries to find proper Postgres
-type for each column.
-Unknown types are silently pushing to output dump;
-ENUM and SET types implemented via user types
-(C source for such types can be found in
-B<libtypes.c> file);
-
-=item * Encloses identifiers into double quotes.
-
-All column and table
-names should be enclosed to double-quotes to prevent
-conflict with reserved SQL keywords;
-
-=item * Converting
-
-AUTO_INCREMENT fields to SERIAL. Actually, creating the sequence and
-setting default value to nextval('seq'), well, you know :)
-
-=item * Converting
-
-KEY(field) to CREATE INDEX i_field on table (field);
-
-=item * The same
-
-for UNIQUE keys;
-
-=item * Indices
-
-are creating AFTER rows insertion (to speed up the load);
-
-=item * Translates '#'
-
-MySQL comments to ANSI SQL '--'
-
-=back
-
-It encloses dump in transaction block to prevent single errors
-during data load.
-
-=head1 COMMAND-LINE OPTIONS
-
-My2pg takes the following command-line options:
-
-=over 2
-
-=item -n
-
-Convert *CHAR DEFAULT '' NOT NULL types to *CHAR NULL.
-Postgres can't load empty '' strings in NOT NULL fields.
-
-=item -d
-
-Add double quotes around table and column names
-
-=item -h
-
-Show usage banner.
-
-=item -s
-
-Do not attempt to convert data. Currently my2pg only tries to convert
-date and time data.
-
-=back
-
-=head1 SIDE EFFECTS
-
-=over 4
-
-=item * creates
-
-file B<libtypes.c> in current directory
-overwriting existed file without any checks;
-
-=item * the same
-
-for Makefile.
-
-=back
-
-=head1 BUGS
-
-Known bugs are:
-
-=over 4
-
-=item * Possible problems with the timestamp data.
-
-PostgreSQL does not accept incorrect date/time values like B<2002-00-15>,
-while MySQL does not care about that. Currently my2pg cannot handle this
-issue. You should care yourself to convert such a data.
-
-=item * Use -s option if your numeric data are broken during conversion.
-
-My2pg attempts to convert MySQL timestamps of the form B<yyyymmdd> to
-B<yyyy-mm-dd> and B<yyyymmddhhmmss> to B<yyyy-mm-dd hh:mm:ss>. It performs
-some heuristic checks to ensure that the month,day,hour,minutes and seconds have
-values from the correct range (0..12, 0..31, 0..23, 0..59, 0..59 respectively).
-It is still possible that your numeric values that satisfy these conditions
-will get broken.
-
-=item * Possible problems with enclosing identifiers in double quotes.
-
-All identifiers such as table and column names should be enclosed in double
-quotes. Program can't handle upper-case identifiers,
-like DBA. Lower-case identifiers are OK.
-
-=item * SET type emulation is not full. LIKE operation on
-
-SETs, raw integer input values should be implemented
-
-=item * B<Makefile>
-
-generated during output is
-platform-dependent and surely works only on
-Linux/gcc (FreeBSD/gcc probably works as well - not tested)
-
-=item * Generated B<libtypes.c> contain line
-
- #include <postgres.h>
-
-This file may be located not in standard compiler
-include path, you need to check it before compiling.
