1.31 Mon Nov 17 21:21:21 UTC 2003 (subversion r7157)
	- $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
	- Fixed many heap buffer overruns.
	- Added support for the get_info() method [GSM]
	- 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 Stosberbg]
		- 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. [GSM]

1.20 Wed Nov 27 16:19:26 2002 (subversion r6949)

		rather than files. Contributed by Garth Webb.
	- Added LISTEN/NOTIFY functionality. Contributed by Alex Pilosov.
	- Added constants for common PostgreSQL data types, plus simple tests to
		make sure that they work. These are exportable via 
		"use DBD::Pg qw(:pg_types);". [David Wheeler]
	- Deprecated the undocumented (and invalid) use of SQL_BINARY in
		bind_param() and documented the correct approach: "bind_param($num,
		$val { pg_type => PG_BYTEA });". Use of SQL_BINARY in bind_param() will
		now issue a warning if $h->{Warn} is true. [David Wheeler]
	- Removed invalid (and broken) support for SQL_BINARY in quote().
		[David Wheeler]
	- Added App::Info::RDBMS::PostgreSQL to the distribution (but it won't
		be installed) to help Makefile.PL find the PostgreSQL include and
		library files. [David Wheeler]
	- Fixed compile-time warnings. [David Wheeler and Jason E. Stewart]
