Interesting, thanks. Yeah I was surprised to hear his skepticism of logical replication, but I've never operated it in production before. Curious for resources on that.
You mean physical, re: skepticism. Just different things. Bulky for "CREATE INDEX" or "VACUUM", but also faster for a lot of things (no decoding) and able to more naturally deal with incomplete transactions.

Most database systems of adequate budget and maturity implement both, for various reasons.
