I'm guessing you must have been using 7.4 or older, because AFAICS this was broken by this 8.0 change: 2004-01-08 21:02 momjian * doc/src/sgml/libpq.sgml, src/backend/nodes/read.c, src/interfaces/libpq/fe-connect.c, src/interfaces/libpq/fe-print.c, src/interfaces/libpq/fe-secure.c, src/interfaces/libpq/libpq-fe.h, src/interfaces/libpq/libpq-int.h, src/interfaces/libpq/pqsignal.c, src/interfaces/libpq/pqsignal.h: Allow libpq to do thread-safe SIGPIPE handling. This allows it to ignore SIGPIPE from send() in libpq, but terminate on any other SIGPIPE, unless the user installs their own signal handler. This is a minor fix because the only time you get SIGPIPE from libpq's send() is when the backend dies. The code appears to unconditionally assume that sigmask() and sigblock() exist. Not a good assumption. AFAICS pqsignalinquire() isn't even used anywhere (at least not in HEAD), so the simplest answer may be to remove it rather than try to fix it. It's in src/interfaces/libpq/pqsignal.c. regards, tom lane
