Ability to advance replication slots
Ability to advance both physical and logical replication slots using a new user function pg_replication_slot_advance(). For logical advance that means records are consumed as fast as possible and changes are not given to output plugin for sending. Makes 2nd phase (after we reached SNAPBUILD_FULL_SNAPSHOT) of replication slot creation faster, especially when there are big transactions as the reorder buffer does not have to deal with data changes and does not have to spill to disk.
