c6221db3c0 Updated text for bitmaps:
<   Bitmap indexes index single columns that can be combined with other bitmap
<   indexes to dynamically create a composite index to match a specific query.
<   Each index is a bitmap, and the bitmaps are bitwise AND'ed or OR'ed to be
<   combined.  They can index by tid or can be lossy requiring a scan of the
<   heap page to find matching rows, or perhaps use a mixed solution where
<   tids are recorded for pages with only a few matches and per-page bitmaps
<   are used for more dense pages.  Another idea is to use a 32-bit bitmap
<   for every page and set a bit based on the item number mod(32).

>   This feature allows separate indexes to be ANDed or ORed together.  This
>   is particularly useful for data warehousing applications that need to
>   query the database in an many permutations.  This feature scans an index
>   and creates an in-memory bitmap, and allows that bitmap to be combined
>   with other bitmap created in a similar way.  The bitmap can either index
>   all TIDs, or be lossy, meaning it records just page numbers and each
>   page tuple has to be checked for validity in a separate pass.

* Allow database recovery where tablespaces can't be created

  When a pg_dump is restored, all tablespaces will attempt to be created
  in their original locations. If this fails, the user must be able to
  adjust the restore process.

f9259bd563 Update wording:
* Allow a database in tablespace t1 with tables created in tablespace t2
  to be used as a template for a new database created with default
  tablespace t2

  All objects in the default database tablespace must have default tablespace
  specifications.  This is because new databases are created by copying
  directories.  If you mix default tablespace tables and tablespace-specified
  tables in the same directory, creating a new database from such a mixed
  directory would create a new database with tables that had incorrect
  explicit tablespaces.  To fix this would require modifying pg_class in the
  newly copied database, which we don't currently do.

f7667e4cfa Update DELETE FROM:
< * Allow DELETE to handle table aliases for self-joins
> * Allow an alias to be provided for the target table in UPDATE/DELETE
276,279c276,282
<   There is no way to create a table alias for the deleted table for use
<   in the DELETE WHERE clause.  The agreed approach is to allow a USING
<   clause to specify additional tables.  UPDATE already has an optional
<   FROM clause for this purpose.
>   This is not SQL-spec but many DBMSs allow it.
>
> * Allow additional tables to be specified in DELETE for joins
>
>   UPDATE already allows this (UPDATE...FROM) but we need similar
>   functionality in DELETE.  It's been agreed that the keyword should
>   be USING, to avoid anything as confusing as DELETE FROM a FROM b.
