Subject: [PATCH] Add casting for numeric/float4/float8 type value
automatically to compensate the lack of automatic conversion functionality of
PostgreSQL server. For example if there's a numeric type binding 1.2567
--> 1.2567::numeric. I hope this change would enable the use of numeric type
in MS-Access etc.
Thanks Hiroki Kataoka for his checking my code.
