I don't have a lot of use for arguments that go "we should remove any
functionality that's not in the spec" ... ISTM that variable lower
bounds are clearly useful for some applications, and even if they had
bugs in earlier releases that's not an argument for removing them.

Interesting thought, but then how do you declare the type of an array
column, or the type of a function argument that's not supposed to range
over every array type? If we can't use an OID to identify a data type
completely, we're going to have lots of problems.
