Yeah, a symlink is impossible to update atomically (on most platforms anyway). Plain file containing the pathname seems better. Another point is that we might not necessarily want *only* the pathname in there. postmaster.pid has accreted more stuff over time, and this file might too. I can see wanting the syslogger PID in there, for example, so that onlookers can detect a totally stale file. (Not proposing this right now, just pointing out that it's a conceivable future feature.) regards, tom lane -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
