If you're not on this month's minor releases, perhaps you should be:

    Reduce memory consumption of logical decoding (Masahiko Sawada)

        Use a smaller default block size to store tuple data received
        during logical replication. This reduces memory wastage, which
        has been reported to be severe while processing long-running
        transactions, even leading to out-of-memory failures.

I recall past updates that fixed other memory leaks in logical
replication, too.

Egad.  Your version-updating strategy seriously needs a rethink.
