This should work but it is better to add a comment before calling CommandCounterIncrement() to indicate that this is for making changes to the relation state visible. Thinking along similar lines, won't apply worker need to be notified of SUBREL_STATE_SYNCWAIT state change by the tablesync worker? -- With Regards, Amit Kapila.
