Thanks for your patch. Here is a comment.

+ elog(DEBUG2, "time-delayed replication for txid %u, delay_time = %d ms, remaining wait time: %ld ms",
+ ctx->write_xid, (int) ctx->min_send_delay,
+ remaining_wait_time_ms);

I tried and saw that the xid here looks wrong, what it got is the xid of the
previous transaction. It seems `ctx->write_xid` has not been updated and we
can't use it.

Regards,
Shi Yu
