Function restore_sigpipe_trap

src/fe_utils/print.c:2948–2954

* restore_sigpipe_trap * * Restore normal SIGPIPE interrupt --- call this when done writing to a * temporary query output file that was (or might have been) a pipe. * * Note: within psql, we enable SIGPIPE interrupts unless the permanent query * output file is a pipe, in which case they should be kept off. This * approach works only because psql is not currently complicated enough to * ha

 * No-op on Windows, where there's no SIGPIPE interrupts.
