Today, I was analyzing this patch w.r.t recent commit c6e1f62e2c and
found that pa_set_xact_state() should set the latch (wake up) for the
leader worker as the leader could be waiting in
pa_wait_for_xact_state(). What do you think? But otherwise, it should
be okay w.r.t DDLs because this patch allows the leader worker to
restart logical replication for subscription parameter change which
will in turn stop/restart parallel workers if required.
