Hmm. At least async.c (pg_notify) deletes the whole directory at startup so it's fine, but for the others (pg_serial, pg_subtrans) I think it'd be saner to keep any "active" files (probably just the latest). I don't remember how pg_snapshot works, but it's probably fine to start with an empty subdir (is it possible to export a snapshot from a prepared transaction?) -- Álvaro Herrera http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
