Thanks for the references.

Note for future: should have tried VACUUM too.

This isn't a bug.  Refer to catalogs.sgml:

        True if this is a table and it has (or recently had) any indexes.
        This is set by CREATE INDEX, but not cleared immediately by DROP
        INDEX. VACUUM clears relhasindex if it finds the table has no indexes.

The flag is only used as a hint that it's worth looking in pg_index to
see what rows there are for the table.

As for "tracking it down", read index_drop().
