Changes 8.2.1:
* Fix crash with SELECT ... LIMIT ALL (also LIMIT NULL)
* "Several /contrib/tsearch2" fixes
* On Windows, make log messages coming from the operating system use
  ASCII encoding
  This fixes a conversion problem when there is a mismatch between
  the encoding of the operating system and database server.
* Fix Windows linking of pg_dump using "win32.mak"
* Fix planner mistakes for outer join queries
* Fix several problems in queries involving sub-SELECTs
* Fix potential crash in SPI during subtransaction abort
  This affects all PL functions since they all use SPI.
* Improve build speed of PDF documentation
* Re-add JST (Japan) timezone abbreviation
* Improve optimization decisions related to index scans
* Have psql print multi-byte combining characters as before, rather
  than output as \u
* Improve index usage of regular expressions that use parentheses
  This improves psql \d performance also.
* Make pg_dumpall assume that databases have public CONNECT
  privilege, when dumping from a pre-8.2 server
  This preserves the previous behavior that anyone can connect to a
  database if allowed by "pg_hba.conf".
