- * pqsignal.c

- * IDENTIFICATION
- *	  src/port/pqsignal.c
- *
- *	We now assume that all Unix-oid systems have POSIX sigaction(2)
- *	with support for restartable signals (SA_RESTART).  We used to also
- *	support BSD-style signal(2), but there really shouldn't be anything
- *	out there anymore that doesn't have the POSIX API.
- *
- *	Windows, of course, is resolutely in a class by itself.  In the backend,
- *	we don't use this file at all; src/backend/port/win32/signal.c provides
- *	pqsignal() for the backend environment.  Frontend programs can use
- *	this version of pqsignal() if they wish, but beware that this does
- *	not provide restartable signals on Windows.
