+</p>
+
+<p>
+Tom Lane pushed:
+</p>
+
+<p>
+- Fix incorrect generation of whole-row variables in planner. A
+ couple of places in the planner need to generate whole-row Vars, and
+ were cutting corners by setting vartype = RECORDOID in the Vars,
+ even in cases where there's an identifiable named composite type for
+ the RTE being referenced. While we mostly got away with this, it
+ failed when there was also a parser-generated whole-row reference to
+ the same RTE, because the two Vars weren't equal() due to the
+ difference in vartype. Fix by providing a subroutine the planner
+ can call to generate whole-row Vars the same way the parser does.
+ Per bug #5716 from Andrew Tipton. Back-patch to 9.0 where one of
+ the bogus calls was introduced (the other one is new in HEAD).
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=6e74a91b2bf0e0032ccd60dd99d6cf47c190c428">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=6e74a91b2bf0e0032ccd60dd99d6cf47c190c428</a>

+
+<p>
+- Update storage.sgml to describe the 9.0 tablespace directory layout.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=c33bfb8b9b0d955b813d99e8f9f5c62c31f7387c">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=c33bfb8b9b0d955b813d99e8f9f5c62c31f7387c</a>
+</p>
+
+<p>
+- Fix ecpg test building process to not generate *.dSYM junk on Macs.
+ The trick is to not try to build executables directly from .c files,
+ but to always build the intermediate .o files. For obscure reasons,
+ Darwin's version of gcc will leave debug cruft behind in the first
+ case but not the second. Per complaint from Robert Haas.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=c75e1436467f32a06b5ab9d594d2a390e7f4594d">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=c75e1436467f32a06b5ab9d594d2a390e7f4594d</a>
+</p>
+
+<p>
+- Don't try to fetch database name when SetTransactionIdLimit() is
+ executed outside a transaction. This repairs brain fade in my patch
+ of 2009-08-30: the reason we had been storing oldest-database name,
+ not OID, in ShmemVariableCache was of course to avoid having to do a
+ catalog lookup at times when it might be unsafe. This error
+ explains why Aleksandr Dushein is having trouble getting out of an
+ XID wraparound state in bug #5718, though not how he got into that
+ state in the first place. I suspect pg_upgrade is at fault there.

+
+<p>
+- Remove obsolete comment, per Josh Kupershmidt.
+<a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=572ab1a542c170ddd2e4c30ef472e13f531b64a4">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=572ab1a542c170ddd2e4c30ef472e13f531b64a4</a>
+</p>

+<p>
+- Improve handling of domains over arrays. This patch eliminates
+ various bizarre behaviors caused by sloppy thinking about the
+ difference between a domain type and its underlying array type. In
+ particular, the operation of updating one element of such an array
+ has to be considered as yielding a value of the underlying array
+ type, *not* a value of the domain, because there's no assurance that
+ the domain's CHECK constraints are still satisfied. If we're
+ intending to store the result back into a domain column, we have to
+ re-cast to the domain type so that constraints are re-checked. For
+ similar reasons, such a domain can't be blindly matched to an
+ ANYARRAY polymorphic parameter, because the polymorphic function is
+ likely to apply array-ish operations that could invalidate the
+ domain constraints. For the moment, we just forbid such matching.
+ We might later wish to insert an automatic downcast to the
+ underlying array type, but such a change should also change matching
+ of domains to ANYELEMENT for consistency. To ensure that all such
+ logic is rechecked, this patch removes the original hack of setting
+ a domain's pg_type.typelem field to match its base type; the typelem
+ will always be zero instead. In those places where it's really okay
+ to look through the domain type with no other logic changes, use the
+ newly added get_base_element_type function in place of
+ get_element_type. catversion bumped due to change in pg_type
+ contents. Per bug #5717 from Richard Huxton and subsequent
+ discussion.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=529cb267a6843a6a8190c86b75d091771d99d6a9">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=529cb267a6843a6a8190c86b75d091771d99d6a9</a>

+- Allow new values to be added to an existing enum type. After much
+ expenditure of effort, we've got this to the point where the
+ performance penalty is pretty minimal in typical cases. Andrew
+ Dunstan, reviewed by Brendan Jurd, Dean Rasheed, and Tom Lane.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=84c123be1de8a9955741e20c9f945571e40c545e">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=84c123be1de8a9955741e20c9f945571e40c545e</a>

+Alvaro Herrera pushed:
+</p>
+
+<p>
+- Remove AtStart_Cache() call in CommandCounterIncrement(). This call
+ was present in the aboriginal code from Berkeley, and has never been
+ touched; it may very well be that it was there to mask effects of
+ bugs in other places and it may no longer be necessary. The removal
+ has been foreseen in a code comment since 2007; this seems to be a
+ good time to test this hypothesis.
+ <a href="http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=17a16663d0c1c70c5c70ba97de6fe2c9c6a3bc07">http://git.postgresql.org/gitweb?p=postgresql.git;a=commitdiff;h=17a16663d0c1c70c5c70ba97de6fe2c9c6a3bc07</a>

+</p>
+
+<p>
+- Make OFF keyword unreserved. It's not hard to imagine wanting to
+ use 'off' as a variable or column name, and it's not reserved in
+ recent versions of the SQL spec either. This became particularly
+ annoying in 9.0, before that PL/pgSQL replaced variable names in
+ queries with parameter markers, so it was possible to use OFF and
+ many other backend parser keywords as variable names. Because of
+ that, backpatch to 9.0.
