- Patch #10622 by Adrian: fixes various PostgreSQL related problems.

  1) Menu problems with Postgres (this is a highly critical 1 line fix)
  2) Archive module fails with Postgres
  3) Postgres setup problems - changes to database.pgsql (although i made these changes myself before finding this patch)
  4) Book module fails with Postgres
  5) Postgres problems following creation of a new type of user - which is actually about a taxonomy.module bug.
  6) Creating accregator_item_table in PostgreSQL
  7) Postgres - Polls not displayed on Poll Page
  8) Blog module has sql errors with postgres

  This should not affect MySQL users (hopefully).
