So can we use this option with the ALTER SUBSCRIPTION command. I think
we can't, which means if the user sets wrong conninfo using ALTER
SUBSCRIPTION command then we don't have the option to detect it like
we have in case of CREATE SUBSCRIPTION command. Since this thread is
trying to add the ability to identify the wrong/missing publication
name specified with the ALTER SUBSCRIPTION command, can't we do the
same for the wrong conninfo?
