Further investigation (not yet complete) suggests that this is a link order
dependency problem. It kicks in because libpq is being linked explicitly
with -lc_r (which should not be necessary or desirable), causing libc and
libc_r to be linked in the wrong order if the executable is _not_ linked
with -pthread.
