Is the fix for > 2GB files already in 6.5.3?

Hello Everyone,

I want to build a prototype system under 32-bit Linux using
a table that would be about 20GB with PostgreSQL. I looked
through the archives and saw talk about a patch for PostgreSQL
to fix a bug with tables > 2Gb. If the system worked, I would
like to migrate over to a 64-bit Alpha system and have tables
> 40GB. Will it work?

Is this patch incorporated into the latest release?

Regards,

Ron King
