changes-in-0001-v2.diff shows the changes to PostgresNode.pm per
Michael's comments, and applies on top of 0001.

I also attach a patch to add a new CREATE_REPLICATION_SLOT option per
Petr's suggestion, so you can request a slot be created
WITHOUT_SNAPSHOT. This replaces the patch series's behaviour of
silently suppressing snapshot export when a slot was created on a
replica. It'll conflict (easily resolved) if applied on top of the
current series.

I have more to do before re-posting the full series, so waiting on
author at this point. The PostgresNode changes likely break later
tests, I'm just posting them so there's some progress here and so I
don't forget over the next few days' distraction.
