+<h2>Applied Patches</h2>
+<p>
+Tom Lane committed:
+</p>
+
+<p>
+- Create an ALTER DEFAULT PRIVILEGES command, which allows users to
+ adjust the privileges that will be applied to subsequently-created
+ objects. Such adjustments are always per owning role, and can be
+ restricted to objects created in particular schemas too. A notable
+ benefit is that users can override the traditional default privilege
+ settings, eg, the PUBLIC EXECUTE privilege traditionally granted by
+ default for functions. Petr (PJMODOS) Jelinek.
+</p>
+
+<p>
+- Change CREATE TABLE so that column default expressions coming from
+ different inheritance parent tables are compared using equal(),
+ instead of doing strcmp() on the nodeToString representation. The
+ old implementation was always a tad cheesy, and it finally fails
+ completely as of 8.4, now that the node tree might contain syntax
+ location information. equal() knows it's supposed to ignore those
+ fields, but strcmp() hardly can. Per recent report from Scott Ribe.
+</p>
+
+<p>
+- Support use of function argument names to identify which actual
+ arguments match which function parameters. The syntax uses AS, for
+ example funcname(value AS arg1, anothervalue AS arg2). Pavel
+ Stehule.
+</p>
+
+<p>
+- Update plhandler.sgml to describe validators and inline handlers for
+ procedural languages.
+</p>
+
+<p>
+- Remove very ancient tuple-counting infrastructure (IncrRetrieved()
+ and friends). This code has all been ifdef'd out for many years,
+ and doesn't seem to have any prospect of becoming any more useful in
+ the future. EXPLAIN ANALYZE is what people use in practice, and I
+ think if we did want process-wide counters we'd be more likely to
+ put in dtrace events for that than try to resurrect this code. Get
+ rid of it so as to have one less detail to worry about while
+ refactoring execMain.c.
+</p>
+
+<p>
+- Split the processing of INSERT/UPDATE/DELETE operations out of
+ execMain.c. They are now handled by a new plan node type called
+ ModifyTable, which is placed at the top of the plan tree. In itself
+ this change doesn't do much, except perhaps make the handling of
+ RETURNING lists and inherited UPDATEs a tad less klugy. But it is
+ necessary preparation for the intended extension of allowing
+ RETURNING queries inside WITH. Marko (johto) Tiikkaja.
+</p>
+
+<p>
+- Improve similar_escape() in two different ways: 1. Stop escaping ?
+ and {. As of SQL:2008, SIMILAR TO is defined to have
+ POSIX-compatible interpretation of ? as well as {m,n} and related
+ constructs, so we should allow these things through to our regex
+ engine. 2. Escape ^ and $. It appears that our regex engine will
+ treat ^^ at the beginning of the string the same as ^, and similarly
+ for $$ at the end of the string, which meant that SIMILAR TO was
+ effectively ignoring ^ at the start of the pattern and $ at the end.
+ Since these are not supposed to be metacharacters, this is a bug.
+ The second part of this is arguably a back-patchable bug fix, but
+ I'm hesitant to do that because it might break applications that are
+ expecting something like "col SIMILAR TO '^foo$'" to work like a
+ POSIX pattern. Seems safer to only change it at a major version
+ boundary. Per discussion of an example from Doug Gorley.
+</p>
+
+<p>
+Alvaro Herrera committed:
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/Makefile, unbreak doc/src/sgml
+ maintainer-clean rule on VPATH builds.
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/Makefile, really unbreak maintainer-clean.
+ (Or rather, unbreak what the previous commit broke)
+</p>
+
+<p>
+- Fix snapshot management, take two. Partially revert the previous
+ patch I installed and replace it with a more general fix: any time a
+ snapshot is pushed as Active, we need to ensure that it will not be
+ modified in the future. This means that if the same snapshot is
+ used as CurrentSnapshot, it needs to be copied separately. This
+ affects serializable transactions only, because CurrentSnapshot has
+ already been copied by RegisterSnapshot and so PushActiveSnapshot
+ does not think it needs another copy. However,
+ CommandCounterIncrement would modify CurrentSnapshot, whereas
+ ActiveSnapshots must not have their command counters incremented. I
+ say "partially" because the regression test I added for the previous
+ bug has been kept. (This restores 8.3 behavior, because before
+ snapmgr.c existed, any snapshot set as Active was copied.) Per bug
+ report from Stuart Bishop.
+</p>
+
+<p>
+- Make it possibly to specify GUC params per user and per database.
+ Create a new catalog pg_db_role_setting where they are now stored,
+ and better encapsulate the code that deals with settings into its
+ realm. The old datconfig and rolconfig columns are removed. psql
+ has gained a \drds command to display the settings. Backwards
+ compatibility warning: while the backwards-compatible system views
+ still have the config columns, they no longer completely represent
+ the configuration for a user or database. Catalog version bumped.
+</p>
+
+<p>
+- Add the new psql command \drds to the psql docs, help and tab
+ completion. I also thank Bernd Helmle for the documentation help on
+ the previous settings patch, which I forgot on the commit message.
+</p>
+
+<p>
+Peter Eisentraut committed:
+</p>
+
+<p>
+- In pgsql/doc/src/sgml/Makefile, clean up the clean rules of the
+ documentation. Most things should be cleaned by "make clean",
+ except the parts that are shipped in the tarball. These rules had
+ gotten a bit out of whack after the various restructurings of the
+ documentation build rules.
+</p>
+
+<p>
+- Use pg_get_triggerdef in pg_dump. Add a variant of
+ pg_get_triggerdef with a second argument "pretty" that causes the
+ output to be formatted in the way pg_dump used to do. Use this
+ variant in pg_dump with server versions >= 8.5. This insulates
+ pg_dump from most future trigger feature additions, such as the
+ upcoming column triggers patch. Itagaki Takahiro.
+</p>
+
+<p>
+Heikki Linnakangas committed:
+</p>
+
+<p>
+- Fix off-by-one bug in bitncmp(): When comparing a number of bits
+ divisible by 8, bitncmp() may dereference a pointer one byte out of
+ bounds. Chris Mikkelson (bug 5101).
+</p>
