Using a plugin producing binary output, I came across this error: =# select data from pg_logical_slot_peek_changes('foo', NULL, NULL); ERROR: 0A000: output plugin cannot produce binary output LOCATION: pg_logical_slot_get_changes_guts, logicalfuncs.c:404
Shouldn't the error message be here something like "binary output plugin cannot produce textual output"? The plugin used in my case produces binary output, but what is requested from it with pg_logical_slot_peek_changes is textual output.
A patch is attached (with s/pluggin/plugin in bonus). Comments welcome.
