It looks like there's no 64-bit version of postgresql for windows: http://swik.net/PostgreSQL/Planet+Postgresql/Magnus+Hagander:+PostgreSQL +vs+64-bit+windows but that the 32-bit version of postgresql works just fine on 32-bit or 64-bit windows, including Vista. Is this correct? There's a thread here about possibly supporting 64-bit postgresql on windows: http://archives.postgresql.org/pgsql-hackers/2008-07/msg00081.php Are there major issues holding that back or is it just a lack of demand? Is there still active work going on?
