You're apparently using the very obsolete and buggy Postgres ODBC driver
that ships with unixODBC --- or at least used to ship with unixOBC; I
think they ripped it out in the most recent release. Get hold of the
postgresql-odbc package (that's what Red Hat calls it, at least, dunno
about whatever distribution you're using) and use the driver from that
instead.

I usually recommend this configuration for the driver definition:

[PostgreSQL]
Description = ODBC for PostgreSQL
Driver = /usr/lib/psqlodbc.so
Setup = /usr/lib/libodbcpsqlS.so
Driver64 = /usr/lib64/psqlodbc.so
Setup64 = /usr/lib64/libodbcpsqlS.so
FileUsage = 1

Depending on which build of postgresql-odbc you're using, the driver
library file might be named psqlodbcw.so instead; but in any case
libodbcpsql.so is not something to trust.
