Thanks!

This feature proposal is currently made of 5 sub-patches:

0001: Add info in WAL records in preparation for logical slot conflict
handling
0002: Handle logical slot conflicts on standby
0003: Allow logical decoding on standby.
0004: New TAP test for logical decoding on standby
0005: Doc changes describing details about logical decoding

I suggest that we focus on one sub-patch at a time.

I'll start with 0001 and come back with a rebase addressing Andres and
Robert's previous comments.

Sounds good to you?

Thanks
