The script analyze_new_cluster.sh output by pg_upgrade contains several "sleep" calls (see contrib/pg_upgrade/check.c). What is the point of this? If the purpose of this script is to get the database operational again as soon as possible, waiting a few seconds doing nothing surely isn't helping.
I could maybe see the point of waiting a bit between the different vacuumdb calls, to catch some breath, but the one before the first call to vacuumdb is highly dubious to me. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
