With all due respect, if pg_migrator does not function in such a way
as to have data-driven composable changes, it's going to bang us up in
the long haul much worse than not branching alphas ever could.
We require that people supply docs with their changes, and it is
totally unreasonable to let them send in catalog changes which do not
include need migration changes. That's how it works in every other
RDBMS outfit that has changes on disk, and we do not need to be the
exception.
If pg_migrator doesn't have this ability, we need to refactor it until
it does, or go with something that can.
Cheers,
David.
