Quick fix so \d indexname works again

-----BEGIN PGP SIGNED MESSAGE-----

I don't think this is worthy of a full patch, but could someone
back off of the new pg_get_expr function in
src/bin/psql/describe.c? It does not seem to work, producing
this message when you try to "\d indexname" in psql:

ERROR: Function 'pg_get_expr(text, oid)' does not exist
Unable to identify a function that satisfies the given argument types
You may need to add explicit typecasts

A quick fix is to remove the pg_get_expr function and replace
it with a simple i.indpred. Either that, or get the pg_get_expr
to work properly (which is beyond me at the moment :)
