have been able to significantly improve the contrib/xml XPath
integration code.

New features:

* XPath set-returning function allows multiple results from an several
XPath queries to be used as a virtual table.
* Using libxslt, XSLT transformations (with and without parameters) are
supported. (Caution: This support allows generic URL fetching from
within the backend as well).

I've removed the old code so that it is all libxml based. Rather than
attach as a patch, I've put the tar.gz (10k!) at
http://www.azuli.co.uk/pgxml-1.0.tar.gz
(all files in archive are xml/....).

I think this is worth replacing the contrib version with, even though
the function names have changed (though the same functionality is
there), because it includes a SRF and some SPI usage, in addition to
linking to an external library. And it isn't a big module! Obviously, I
understand that people might prefer to move it elsewhere, or might have
reservations about replacing an existing contrib module with an
incompatible one. I'm open to suggestions.

support for 'week' within the date_trunc function.

Within the patch I added a couple of test cases and associated target
output, and changed the documentation to add 'week' appropriately.

schema-safe.  Make it so, and improve the internal support for knowledge
of server version.

* Mostly, casting etc to remove compilation warnings in win32 only code.

* main.c: set _IONBF to stdout/stderr under win32 (under win32, _IOLBF
defaults to full buffering)

* pg_resetxlog/Makefile: ensures dirmod.o gets cleaned (got bitten by
this when, after "make clean"ing, switching compilation between Ming +
Cygwin)

float8 types. This begins the deprecation of this feature: in 7.6,
this input will be rejected.

Also added a new error code for warnings about deprecated features,
and updated the regression tests.

type text was not wrapped as <type>text</type>.

- Added check for multidimensional array usage.

the FROM clause and an example to the UPDATE reference page, and make
a few other SGML tweaks.

object types, rather than by OID.  This should help ensure consistent
dump output from databases that are logically the same but have different
histories, per recent discussion about 'diffing' databases.  The patch
is bulky because of renaming of fields, but not very complicated.
Also, do some tweaking to cause BLOB restoration to be done in a better
order, and clean up pg_restore's textual output to exactly match pg_dump.

correctly passed as:

FWIW, "fixes" a large (> 20) tests under Win32.

paste ...

The former coding failed if the cast function was not in the pg_catalog
schema.  How'd this escape detection?

simplistic; it recognized SELECT * FROM but not SELECT * FROM LIMIT.

Backpatch to 7.4.X.

to the discussion of planner statistics in the documentation for the
default_statistics_target GUC var.

equivalent sort expressions to use was broken: you can't just look
at the relation membership, you have to actually grovel over the
individual Vars in each expression.  I think this did work when it
was written, but it was broken by subsequent optimizations that made
join relations not propagate every single input variable upward.
Must find the Var that got propagated, not choose one at random.
Per bug report from Daniel O'Neill.
