I get it. I think having errdetail explaining the possible cause of
the error is wanted here, something like:
errmsg("cannot invalidate replication slots when in binary upgrade mode"),
errdetail("This can be caused by overriding \"max_slot_wal_keep_size\"
using command line options."));
errhint("Do not override or set \"max_slot_wal_keep_size\" to -1 ."));
Thoughts?
