I don't know enough about other databases to judge this. But if only
MySQL and PostgreSQL support it and then maybe in very different ways I
see little sense in having it in an abstraction layer as emulating this
(in a more or less sane way) is impossible.

Having it optional with the given structure is stupid.

Having it optional with another structure might probably be ok, but then
it should be similar at least for databases which support it and not be
implemented completely different for each and every.
