Unfortunately, there is no "alter sequence" syntax in Postgres as of yet.
You could emulate this by having a trigger address a config table of
some sort where you have a column defining the increment size.  Then all
you'd have to do is change the increment size.  Sadly, that would give
you a performance hit on inserts.

Postgres has a ton of missing "alter" syntax, you just have to learn to
live with it.  I'm not all that happy with it, either.
