This is not a bug.  -t selects the table only, not associated indexes.

But from a user's perspective, that behavior seems kind of useless.

The associated sequence !=3D indexes on the same table, but yes, it's a lit=
tle annoying
sometimes.

Well, I can see the possible usefulness of a switch that says "give me
this table and all associated indexes/constraints" (other than FK
constraints, likely).  But it would be something new, not -t.
