psqlodbc.dll
psqlodbc25.dll

What's the difference ?

The different versions of the ODBC protocol they support.

Thanks .

There are different versions of the ODBC standard (v2, v2.5, v3 ...) - IIRC
there are details somewhere on Microsoft's sites (it's their standard). If in
doubt, use the middle-one.

I believe the psqlodbc30w.dll also supports multi-byte character sets, but
don't quote me on that.

Thanks for your prompt reply .

I use psqlodbc30w.dll one week ago .But I found it caused my
Delphi client program to fail in the running progress frequently.
I replaced it with the middle one ,there was no any problem .

My database was postgres7.3.4 on redhat linux 9 .
My client program was compiled with Delphi 6(SP2) using
ADO-ODBC connection .
