Release date: 2005-10-04
This release contains a variety of fixes from 8.0.3. For information about new features in the 8.0 major release, see Section E.75.
A dump/restore is not required for those running 8.0.X. However, if you are upgrading from a version earlier than 8.0.3, see the release notes for 8.0.3.
Fix error that allowed VACUUM to remove ctid chains too soon, and add more checking in code that follows ctid links
This fixes a long-standing problem that could cause crashes in very rare circumstances.
Fix CHAR() to properly pad spaces to the specified length when using a multiple-byte character set (Yoshiyuki Asaba)
In prior releases, the padding of CHAR() was incorrect because it only padded to the specified number of bytes without considering how many characters were stored.
Force a checkpoint before committing CREATE DATABASE
This should fix recent reports of "index is not a btree" failures when a crash occurs shortly after CREATE DATABASE.
Fix the sense of the test for read-only transaction in COPY
The code formerly prohibited COPY TO, where it should prohibit COPY FROM.
Handle consecutive embedded newlines in COPY CSV-mode input
Fix date_trunc(week) for
dates near year end
Fix planning problem with outer-join ON clauses that reference only the inner-side relation
Further fixes for x FULL JOIN y ON true corner cases
