- Link the entries in the table to the catalog heading

- Wrap them in the <database class="table"> tags, since thats what they
are (no markup rules for this, so it inherits from parent -- no style
change)
- Mention that pg_database, pg_shadow, and pg_group are global, and the
rest are local to the specific DB. (I believe this is correct).
