The fix for locales and plperl in 7.4.11 might make an REINDEX necessary.

- Fix error that allowed VACUUM to remove ctid chains too soon, and add

multiple-byte character set (Yoshiyuki Asaba)
- Fix the sense of the test for read-only transaction in COPY

the inner-side relation
- Further fixes for x FULL JOIN y ON true corner cases

parameter

index on column a
- Improve robustness of datetime parsing
- Improve checking for partially-written WAL pages
- Improve robustness of signal handling when SSL is enabled
- Don't try to open more than max_files_per_process files during
postmaster startup
- Various memory leakage fixes
- Various portability improvements
- Fix PL/PgSQL to handle var := var correctly when the variable is of
pass-by-reference type
- Update contrib/tsearch2 to use current Snowball code
Changes from 7.4.9 to 7.4.10:

or in a failed transaction (Tom)
- Fix character string comparison for locales that consider different
character combinations as equal, such as Hungarian (Tom)

available salt space for MD5 and XDES algorithms (Marko Kreen, Solar
