- Patch #40532 by wtanaka: use longblog for data in the cache.  Is reported to fix utf-8 problems and improves consistency with PostgreSQL.

  1. fixed problem with long URLs being truncated (and causing errors)
  2. added CREATE UNIQUE INDEX to prefix.sh
  3. changed totalcount from int to bigint to prevent overflow
  4. unifies index names, syncs with database.mysql

  Updated changelog.

- Modified patch #40534: improved themability of forum icons (makes it possible to use animated gifs) + removed forum setting.

- Patch #40393 by Richard: corrected permissions of menu/path settings on the content submission form.

- Patch #40524 by drumm: made sure that visiting the admin/modules page does not break your setup if you haven't run udpate.php yet.

  - When user #1 creates an account (we can assume this happens only once), system.module's schema version is set to the latest availiable.
  - system_get_files_database() now includes a 'schema_version' child of each file object.
  - That new information is re-saved when Drupal re-populates the system table.
  - An array of newly-enabled modules is built, module_list() is reloaded, and the schema versions of each newly-enabled module are set to the most recent availiable. If the schema version is already set (presumably from a previous installation) it is not changed.

- Patch #40303 by Cvbge: drop old columns for PostgreSQL and fixed some PostgreSQL problems in the update script.

  There are a number of small optimizations we could add; like, we should never do more lookup queries than the number of unique URL aliases in the database.  When the size of the static cache equals the number of unique URL aliases in the database, we can stop doing lookups.  I think this could be implemented with a 2-line change.  Takers?

- Patch #38889 by rkerr: db_error and db_affected_rows did not work properly in presence of multiple database connections.
