If that's the only consideration for this, well, that's certainly quite
straight-forward to change in the other direction too. The new function
suggested by Andres actually makes it really easy to get a textual list
of all the role attributes which a role has from the bitmask too. I was
more concerned with the on-disk and C-level structure and size than
about the time required to get at the value of each bit at the
SQL-level.
