Make pg_dump emit only CREATE INDEX sentences with two-param format.  In
fact I think it would make sense to convert internally the one-param
format to two-param, before hitting the catalogs.

This would also solve your problem about usability of WHERE clauses, if
you rewrite the one-param calls to two-params before the optimizer kicks
