Logical replication row filtering is a much better alternative to the ship and drop approach.

Interesting. I've been thinking about it as well. I wrote some code to prototype it here: https://github.com/pgdogdev/pgdog/blob/main/pgdog/src/backen...

We used it to shard a database at Instacart after your time instead of the “replicate everything and drop the data on the shard approach”. That combined with dropping all the indexes (minus the primary key) worked well for the data copy/initial sharding.
