		multi-column keys. [Greg Sabino Mullane]
	- Rewrote the primary_key_info() and primary_key() methods to

	- Switched commit behavior from commit->execute->begin
		to begin->execute->commit
		[xelah-junk@xelah.com]
	- Made the _pg_use_catalog subroutine use {private_dbgpg}.

		[Greg Sabino Mullane]

		Servers with a low client_min_messages are handled correctly.
		[Greg Sabino Mullane]

	- Added required fields to the type_info() method:
		SQL_DATA_TYPE, SQL_DATETIME_SUB, and INTERVAL PRECISION
		[Greg Sabino Mullane]
	- Fixed bug where the table_attributes() method was incorrectly
		removing the NULLABLE column. [Greg Sabino Mullane]
	- Fixed bug where case was not being preserved by the
		foreign_key_info() method [Greg Sabino Mullane]
	- a fetch on any column that had a type that did not have an entry
		in the type_info array would segfault DBD::Pg.
		(CPAN bugs #4818,4432) [Rudy Lippan]
	- Duplicate rows bug with column_info() REMARKS has been fixed. However,
		support for Postgres 7.1.x which worked briefly for 1.31 has now been
		dropped for this feature. (Mark Stosberg)
	- Bumped required Perl version to 5.6.1 in Makefile.PL. We were already
		already requiring 5.6.1 for Pg.pm since 1.31.
	- Removed extra "return" statement in quote.c to make Solaris happy
		(CPAN bug #4419) [Rudy Lippan]
	- Changed get_info(29) to return (") instead of (\")
		(CPAN bug #4829) [Greg Sabino Mullane]

1.31 Mon Nov 17 21:21:21 UTC 2003
	- $dbh->{TYPE} now returns SQL_TYPE_TIMESTAMP instead of 1114 for
		timestamp columns. (In 1.31_x {x| x<8} $sth->{TYPE} returned 0
		but reported by ["Hirche, Joachim" <Joachim.Hirche@cimconcepts.com>]).
	- Raised required versions to Perl 5.6.1 and DBI 1.35
	- Fix syntax error related to pg_server_version (CPAN bugs #2492,2755,3121)
	- Cache multiple calls to pg_server_version.
	- Notice messages generated by the database now use the perl
		warning mechanism instead of going to stderr.
		[Dominic Mitchell <dom@semantico.com>]
	- $dbh->prepare() rewrites the SQL statement into an internal form,
		striping out comments and whitespace, and if PostgreSQL > 7.3 takes the
		stripped statement and passes that to Postgres' PREPARE statement,
		then rewrites the statement as 'EXECUTE "DBD::PG::cached_query n"
		($1, $2, ... $n, $n+1)' for DBD::Pg's execute.
		-- Currently disabled until PREPARE works a little better
	- Allows the use of :n and :foo bind params. So:
		(SELECT * FROM foo WHERE 1 = :this and 2 = :that) will now work.
	- Complains on execute when unbound bind params are submitted
		(instead of defaulting to NULL)
	- Switched over to use driver.xst.
	- pg_error() removes \n's rather than truncating the message on the first \n.
	- Fixed statement scan problem where the preparse of
		"SELECT foo[3:33] from bar" was scanning :33 as a placeholder
	- Moved the quoting of bind values out of execute() and into
		bind -- as there is no need to requote the value every time execute
		is called.
	- :veryverylongplaceholdername == Long walk, short pier -- fixed.
	- quote() is now in C and uses same code as bind_param.
	- Quoting and dequoting now use libpq quoting functions where available
		(I still need to take the libpq functions swiped out of quote.c and move
		it into libpqswip.c with license info &c., and switch ifndefs to ifdefs)
	- bind_param() will convert from 1,0 to TRUE/FALSE when pg_type
		is PGBOOLOID.
	- Fixed many heap buffer overruns.
	- Added support for the get_info() method [Greg Sabino Mullane]
	- Added tests for POD validation [Mark Stosberg]
	- Several improvements to column_info, including:
		- Fixed column_info so NULLABLE field shows correctly. [kevin@sysexperts.com]
		- REMARKS field works now [Mark Stosberg]
		- COLUMN_DEF fixed
		- COLUMN_SIZE fixed
		- pg_constraint column added to display column constraints
		- additional documentation and tests added
	- make test is now more intelligent and will bail out early if
		db connection fails. [Greg Sabino Mullane]
