Hello
The patch can be applied to PG master branch without problem and it passed regression and tap tests. I manually tested this feature too and the last conn error is correctly shown in the pg_stat_get_wal_receiver output, which does exactly as described. I think this feature is nice to have to troubleshoot replication issues on the standby side.
thank you
Cary Huang
