Re: Design for In-Core Logical Replication

First, I'd like to emphasise that logical replication has been stalled
for ages now because we can no longer make forward progress on core
features needed until we have in-core logical replication (they're
dismissed as irrelevant, no in core users, etc) - but we have also had
difficulty getting logical replication into core. To break this impasse
we really need logical replication in core and need to focus on getting
the minimum viable feature in place, not trying to make it do everything
all at once. Point-to-point replication with no forwarding should be
just fine for the first release. Lets not bog this in extra "must have"
features that aren't actually crucial.

I don't think any person who actually works on postgresql with customers and clearly deals with "competition" can state with any sanity that we don't need logical replication in core.
