What makes it unreasonable? How are constraints handled differently that
makes it reasonable for them?

I can think of two ways to handle this...

a) Leave indexes in pg_class and add a field to indicate the
table/object that the item belongs to. relnamespace could very possebly
be used for this.

b) Create a seperate table for indexes.

Of course, it's trivial to change a few system tables, it's changing
everything else in code that will be the fun part. :) I'm hoping that
plan a wouldn't impact the internals too badly, but I really have no
idea.

FWIW, DB2 and (I think) Oracle both use a global namespace for indexes.
Sybase and (I think) MSSQL don't. I really don't understand why you'd
want indexes in a global namespace and wish IBM and Oracle would change
their products.
