Correct, and with dblink on logical slots. The gotcha is making the logical slots persistent in your network config.
I have done db link from one table to another on my primary and then use that table as the source for processing data
orwhatever.
But you will have to do custom work.
The most annoying part of this is the MSSQL ::Postgres inconsistencies such as date, numeric and float , bit::bool
types.

I don't know how those two are implemented--but for background on what is possible, you might want to read up on
PostgreSQLlogical replication slots. Essentially, one can write a plug-in which has access to a serialized stream of
allupdates being applied. There are examples which exist. So one could write such a thing that pushes to MSSQL, or one
coulduse such a thing which publishes change stream as JSON, and develop something to push this to MSSQL. Not
suggestingthat *you* have to this--just that it's likely tools are based on this, and it would be good for your
understanding.
