I may be missing, of course, but a relation is switched to
SUBREL_STATE_READY only once a sync happened and its state was
SUBREL_STATE_SYNCDONE, implying that SubscriptionRelState->lsn is
never InvalidXLogRecPtr, no?
For instance, nothing happens when a
Assert(!XLogRecPtrIsInvalid(rstate->lsn)) is added in
process_syncing_tables_for_apply().
