Several /contrib/tsearch2 fixes (Teodor)

On Windows, make log messages coming from the operating system use ASCII encoding (Hiroshi Saito)

Fix Windows linking of pg_dump using win32.mak (Hiroshi Saito)

Fix planner mistakes for outer join queries (Tom)

Fix several problems in queries involving sub-SELECTs (Tom)

Fix potential crash in SPI during subtransaction abort (Tom)

Improve build speed of PDF documentation (Peter)

Re-add JST (Japan) timezone abbreviation (Tom)

Improve optimization decisions related to index scans (Tom)

Have psql print multi-byte combining characters as before, rather than output as \u (Tom)

Improve index usage of regular expressions that use parentheses (Tom)

This improves psql \d performance also.
