Question for other PostgreSQL users
On your moderately busy DB, how many different tables might receive at
least one change/DML during a 10 second window?
10? 50? 100? More? Ballpark guess off the top of your head.
I'm in a discussion & there's questions about whether it's unusual to have

sql commands. I’d check out pglogical from 2nd quadrant; this should be
supported on RDS 9.6 iirc.
