Feature request: logical replication #1080

It would be great if we could use Skunk for native Postgres CDC. it could have a great advantage over embedded debezium, because it still uses polling so isn't great for latency-sensitive applications.

@n3ziniuka5 Thanks for the suggestion! I'm not familiar with Postgres CDC. Do you have an idea what would be involved in adding support to Skunk?

Skunk already supports streaming, e.g. NOTIFY/LISTEN channels, and I think users could create publications and replication slots themselves, so you would only need to understand Postgres logical decoding. I say "only", but that's probably a big amount of work.
