PFA a patch that adds a new function, pg_move_replication_slot, that makes it possible to move the location of a replication slot without actually consuming all the WAL on it.

This can be useful for example to keep replication slots in sync between different servers in a replication cluster.

(Obviously this is intended for 11, as we're well into the freeze for 10. Just to be clear. so I'll go add itto the summer commitfest)
