Well as it happens, a table "foo" with a serial field "bar" will have a
sequence called "foo_bar_seq" - so you can figure it out from the field name.
I don't know if this is *guaranteed* to always be that way, but it's been
that way for a while, and I can't see the developers changing it in a hurry.

Be careful if the name gets too long and gets trimmed.
