In postgreSQL version 8.4 it seems that you can place the db server into warm standby mode with the following setting in recovery.conf
restore_command = 'pg_standby archiveDir %f %p %r'
In postgreSQL version 9.5 I see the same option, but I also see what appears to be an alternative syntax in recovery.conf:
standby_mode = (boolean) trigger_file = (string)
So is this new syntax an alternative to the old syntax (both are accepted by PGSQL)? Any benefit to the new syntax?
Does the new syntax mean that I can use the restore_command setting as well (to use my own copy command)?
