I am only using a "C" based client with libpq. But, I did not explicitly turn
anything off like perl or tcl. Are these off by default?
Is there some way to check in the gdb or compile log?

Are you using plperl or pltcl? The backend shouldn't go multithreaded,
but we've seen problems with those interpreters causing it to happen.
(I suppose other language interpreters like python might be risks as
well, but those two are the only ones trouble has been reported with.)
