When using something like InitialisePostgres3(), if the approximate

No.
The reason that I ask is that it appears that the most efficient way of
getting libpq.dll for Windows is to install the ODBC drivers, and they go
into a directory typically named like C:\Program Files\psql\ODBC\xxxx\bin
where xxxx is a version number.
Maybe the installer writes something in the registry, in which case you
could try that first.
There's a problem with this on (at least some versions of) Windows: if you
use InitialisePostgres3() it will find libpq.dll but not other libraries such
as ssleay. A workable hack appears to be to cd to the directory that contains
the DLLs before attempting to establish the database connection.
I consider this an installation problem, not something that must be catered for
in FPC.
Michael.
