That argument only holds water if they all support it with the same
semantics, a fact not in evidence. I'm not impressed by whether they
all have things they call synonyms, unless they all work alike. What
are their approaches to permissions? What happens if the referenced
object is dropped or modified? Can you make a synonym to something that
doesn't exist yet? What sorts of objects can have synonyms?
"all" might also be a bit of an overstatement. AFAIK Sybase at least
doesn't have these.
Even if they don't all have precisely the same semantics, though, is
there an objection in principle to providing synonyms?
