Thank you for reviewing the patch!
Actually, that comment is inspired by the comment just below comment.
ISTM it's better to fix both if grammar of them is not appropriate.
+
+ /*
+ * If we've sent a record that is at or beyond the flushed point, we
+ * have caught up.
+ */
+ if (sentPtr >= GetFlushRecPtr())
+ WalSndCaughtUp = true;
}
else
{
/*
* If the record we just wanted read is at or beyond the flushed
* point, then we're caught up.
*/
if (logical_decoding_ctx->reader->EndRecPtr >= GetFlushRecPtr())
{
Attached a updated patch. Please review it.
