The problem is that after the ALTER SUBSCRIPTION tap_sub SET PUBLICATION command, we didn't wait for the new walsender to start on the publisher. Immediately after ALTER, we performed Insert and expected it to replicate. However, the replication could start from a point after the INSERT location, and as the subscription isn't copying initial data, we could miss such an Insert. The fix is to wait for connection to be established between publisher and subscriber before starting DML operations that are expected to replicate. As per CI.
