Hi -- sorry, I didn't realize you were, and it was entirely my mistake
about what the libpq functions did.
In the end, my problem was mixing code compiled with -fPIC and code
complied without it. That seemed to generate a memory leak in code which
was actually disconnected from Postgres. However, diagnosing it turned
out to be very difficult given that the code itself was fine, and after
some tests I incorrectly came to the conclusion about what PQgetvalue()
returned. (I still don't know why I didn't get core dumps, but probably
what happened was that my test didn't try to free as much as I had thought
it did.)
Thanks,
