Not on that much evidence; but trying to pass a libpq connection across
a fork is usually risky. The trouble is that both parent and child
processes now hold copies of the open socket connection, but only one of
them can safely work with it. It could be that you've closed the libpq
connection in one process and that killed its usability in the other.
