thank you all for your advice. I've been investigating this a little more
and finally it turned out it's not a bug in libpq although I got confused
by going deep as several libpq functions. The bug was really on our side
after trying to use connection pointer after calling PQfinish(). The code
is pretty complex so it took some time to investigate however I would like
to apologize for "blaming" libpq instead of our code.
Usually using a tool like valgrind is quite helpful to find issues like
that, because it'll show you the call-stack accessing the memory and
*also* the call-stack that lead to the memory being freed.
Well, I've tried but I was unable to locate the issue so I had to
investigate the code our little further and finally I've been able to
find the issue.
