33296c1f96 Changes 8.2.9:
* Make pg_get_ruledef() parenthesize negative constants (Tom)
  Before this fix, a negative constant in a view or rule might be
  dumped as, say, -42::integer, which is subtly incorrect: it should
  be (-42)::integer due to operator precedence rules. Usually this
  would make little difference, but it could interact with another
  recent patch to cause PostgreSQL to reject what had been a valid
  "SELECT DISTINCT" view query. Since this could result in pg_dump
  output failing to reload, it is being treated as a high-priority
  fix. The only released versions in which dump output is actually
  incorrect are 8.3.1 and 8.2.7.
* Make "ALTER AGGREGATE ... OWNER TO" update pg_shdepend (Tom)
  This oversight could lead to problems if the aggregate was later
  involved in a "DROP OWNED" or "REASSIGN OWNED" operation.

newer versions.  This gives a performance improvement on client-side,
especially on NetBSD -current.

  security reasons
* Do not let "/contrib/intarray" try to make its GIN opclass the
  default (this caused problems at dump/restore)

52694bfff8 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".

5e43280b23 Replace mk/bsd.prefs.mk includes with bsd.fast.prefs.mk includes.
The redundant parsing of bsd.prefs.mk is mostly avoided now and
parse time e.g. for x11/kdebase3 gets reduced by up to 10%.
