Thread: Using PostgreSQL 32bit dlls in 64-bit code?

Hi,

We are considering to use postgreSQL for our 64-bit code development
for Windows XP 64 bit machine.

As 64-bit postgreSQL is not available for Windows, we can only use
postgreSQL's 32bit dlls.  In that case, can we just call postgreSQL's
functions in our 64-bit code?   Or do we need to write a wrapper
around postgreSQL's 32bit dlls somehow?

Any pointer will be much appreciated.  Thanks.

you can't call 32bit libraries from 64bits (or visa versa) without going
through all kinda complex data thunking.     you would need a wrapper,
or better, assuming you're coding native libpq calls, recompile libpq
for windows x86_64.   the database server could remain 32bit.
