pgsql: Use a bitmask to represent role attributes

Use a bitmask to represent role attributes

The previous representation using a boolean column for each attribute
would not scale as well as we want to add further attributes.

Extra auxilliary functions are added to go along with this change, to
make up for the lost convenience of access of the old representation.

Catalog version bumped due to change in catalogs and the new functions.
