Wouldn't that require thread safety on the part of libpq? Versions 8.4 and earlier requires the library to be configured with the option --enable-thread-safety, although version 9.0 has thread safety turned on by default. http://www.postgresql.org/docs/8.4/static/libpq-threading.html http://www.postgresql.org/docs/9.0/static/libpq-threading.html At least the Ubuntu PostgreSQL 8.4 packages are compiled with thread safety, but I can't speak for other distributions.
