I did not conduct much more test but from what I've seen, it looks like the
ODBC driver is in the doldrums, not PG. For example, when I run my software
on Windows rather than Linux, everything just works as expected. Sorry for
And btw, I use ODBC because my target DB is Oracle and I've been requested to
access it throguh ODBC. So, because I don't have Oracle, I do most of my
development with PG and then I'll port to Oracle. Since I'm doing "simple"
stuff, PG is almost 100% compatible with Oracle. (and before you ask, no,
they don't give me the proper dev environment, bastards :))
Thanks for all the answers.
