We perhaps don't need -lpthread for creating libpq, but only for ecpg.
However, now that we have used thread locking for SIGPIPE, we are now
calling pthread from libpq, but only 7.5.
However, I still don't understand why the user is seeing a problem and
what rewrite he thinks is necessary for his application because pthread
is linked in.
