There is a trick you could use here with two hooks: the planner hook and the utility hook. The idea is to filter all queries and refuse them when RecoveryInProgress() is satisfied. The parsed tree can be used in the planner hook to check for those functions and accept them. -- Michael -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
