This looks like malloc() complaining because something has corrupted its
bookkeeping data, which generally means that something previously wrote
past the end of a malloc'd data chunk, or tried to write into an
already-freed chunk. The odds are very high that the bug is in your
program rather than libpq, though, because no such problems have been
found within libpq recently.
valgrind is a fairly useful tool for tracking down such issues.
