Without such an option, a user cannot easily trigger the "normal" promotion when we find some problems in fast promotion. In this case, a user needs to create the "promote" file and send the SIGUSR1 signal to postmaster by hand. Or needs to execute pg_ctl promote by using old version (e.g., 9.2) of pg_ctl. Seems confusing. Regards, -- Fujii Masao -- Sent via pgsql-hackers mailing list ([email protected]) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
