The alias route gets me thinking about Oracle synonyms.. That'd be nice
to have in PG for a number of object types. Most recently I was wishing
I could create a schema synonym, though being able to do tables/views
would have worked as well in that case, just a bit more work.

I like the concept. Not sure how much I'd end up using it, personally.
