Thread: Postgres 32bit on Windows 64bit, related components

Any specific reasons for choosing Windows? Once in a while, I see someone 
posting issues about PostgreSQL on windows and replies which go 'Windows? 
hmmm...not sure about that ..". Of course, those were not questions about 
queries/query tuning etc. Those get answered. These questions mostly deal 
with  crashes/recovery/security related and so on.

Hi Jayadevan,

We're adding to our server farm, which is Windows. We use Windows as our application is .NET based, and related
componentsin our systems require Windows. Switching to *nix is not an option. 

I'm just after some assurance that all the extra 32bit components in Postgres will run OK under 64bit Windows. I mean
allegedly*anything* 32bit is supposed to run under 64bit, but it's not always this simple in practice. 

-Brendan

In general, as long as you run *all* components in 32-bit mode, things
will be fine. It's only when you start mixing 32 and 64-bit that
things can go bad. You can have 64-bit client/32-bit server or the
other way around, but mixing 32 and 64 bit components *within* the
server or *within* the client will make things a lot harder.

Also note that PostgreSQL 9.0 will be available natively 64-bit on Windows.

Yeah, but Slony/PostGIS won't.

Can anyone confirm whether an 32bit installation of all these components will work together successfully in a 64bit Windows environment?

Npgsql before 2.09 had a Problem when using SSPI-authentication on Windows 64 but you should't have any problem with recent versions.
