Tom Lane	e8f1097361	Endeavor to make pgstats buffer process (a) safe and (b) useful. ... Make sure it exits immediately when collector process dies --- in old code, buffer process would hang around and compete with the new buffer process for packets. Make sure it doesn't block on writing the pipe when the collector falls more than a pipeload behind. Avoid leaking pgstats FDs into every backend.	2001-08-05 02:06:50 +00:00
Tom Lane	dad8e410d0	Fix handling of SIGCHLD, per recent pghackers discussion: on some ... platforms system(2) gets confused unless the signal handler is set to SIG_DFL, not SIG_IGN. pgstats.c now uses pqsignal() as it should, not signal(). Also, arrange for the stats collector process to show a reasonable ID in 'ps', rather than looking like a postmaster.	2001-08-04 00:14:43 +00:00
