Well if you do the popular technique of doing everything through stored
procedures (in our case plpgsql functions) then you can have those functions
check. I don't like that approach myself though.
You could also have a column with a default value which uses the sslinfo to
retrieve the common name. Or you could have a trigger which throws an error if
that function doesn't return valid value. Either way you would be doing a lot
more work than necessary since it would be checking every row, not once per
session. And it wouldn't stop selects.
I think what you really want is a ON CONNECT trigger for this.
