Probably both, but if it's done there should be options to:
.) disable it completely or by table/database or even threshold or
disk free parameters (indicies can be large)
.) log any auto-created databases to inform the DBA.
.) if disabled optionally log when it would have created an index on
the fly. (suggest an index)
.) expire old and unused auto-created indecies.
Generally Postgresql assumes the user knows what he's doing, but
it couldn't hurt too much to provide an option to have it assist
the user.
