The time zone probe logic involves reading every file under /usr/share/zoneinfo (or wherever you have the Olson tz database installed). There are a couple thousand of those in a typical Linux installation. In a cold-boot situation where none of that data is already swapped in, it's not unusual for this to take five seconds or more. Now that may or may not seem like a lot, but it's more than enough to cause many startup scripts to conclude that the postmaster has failed. The hacks we'd built up to deal with this eventually became insupportable. We're not going back. I suggest you consider ways to adjust your server-migration process. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
