Here's a v33, where pg_repackdb has been removed, per multiple
discussions off-list. This is not a statement that we will never have
such a tool; just that for the time being we should not let ourselves be
distracted by it. If we have time to get something done about it for
v19, then it's fine to bring it back; but I kinda doubt it. I think
getting bits done including the addition of the CONCURRENTLY option
trumps that. We can add it in v20 if we decide to; no great loss.
I didn't include Antonin's 0006 "Use multiple snapshots to copy the
data" either. It seems a bit too experimental yet. I think it would be
good to have it in v19 also, but it seems less critical than the rest.
I haven't looked at Mihail's patch downthread either.
