Hi, all

We use 32bit postgres PG11 in our product for X86_64 platform, Now we want to add new process which is 64bit
to access the 32bit progres using 64bit libpq.

I tried to access the PostgresDB 32bit, with 64bit libpq and it works very nice.
So my question is, can we use 64bit lippq to access 32bit PostgresDB in X86_64 platform?

Thank you,
BoChen
