Unfortunately your patch failed to apply to current master branch.

$ git apply ~/mutated_table.patch 
error: patch failed: src/streaming_replication/pool_worker_child.c:1032
error: src/streaming_replication/pool_worker_child.c: patch does not apply

It tried with patch command and it seems failed here:

Need rebase?
