Thread: pg_basebackup and replication slots
Hello, The fact that pg_basebackup doesn't use replicaiton slots, is that a technical limitation or just a, "we need a patch"?

It is not in 9.5 but it is already there.

pg_basebackup: Add --slot option
This option specifies a replication slot for WAL streaming (-X stream), so that there can be continuous
replicationslot use between WAL streaming during the base backup and the start of regular streaming replication.

I believe it does, but only in master so far, not even in 9.5: http://www.postgresql.org/docs/devel/static/app-pgbasebackup.html

Given the rest of the thread.... any possibility whatsoever that it'd be
backpatched into 9.5 before release? Guess it'd be a very welcome addition....

This will be available in 9.6. 9.5 is aimed at being stabilized now, so no new features are added at this point. -- Michael

Of course we won't put it in the main tree but this might be something worth leaving outside (until 9.6).
