reflects the changes in the tablefunc-fix patch that I sent in the other
day. It also refers to "see contrib/tablefunc for more examples", which
is next on my list of things to finish and submit.

COPY x (a,d,c,b) from stdin;
COPY x (a,c) to stdout;
as well as the corresponding changes to pg_dump to use the new
functionality. This functionality is not available when using
the BINARY option. If a column is not specified in the COPY FROM
statement, its default values will be used.
In addition to this functionality, I tweaked a couple of the
error messages emitted by the new COPY <options> checks.

Implements between (symmetric / asymmetric) as a node.
Executes the left or right expression once, makes a Const out of the
resulting Datum and executes the >=, <= portions out of the Const sets.
Of course, the parser does a fair amount of preparatory work for this to
happen.
Rod Taylor
Conway (BuildTupleFromCStrings sets NULL for pass-by-value types when
intended value is 0). It also implements some other improvements
suggested by Neil.

conversion procs and conversions are added in initdb. Currently
supported conversions are:
UTF-8(UNICODE) <--> SQL_ASCII, ISO-8859-1 to 16, EUC_JP, EUC_KR,
EUC_CN, EUC_TW, SJIS, BIG5, GBK, GB18030, UHC,
JOHAB, TCVN
EUC_JP <--> SJIS
EUC_TW <--> BIG5
MULE_INTERNAL <--> EUC_JP, SJIS, EUC_TW, BIG5
Note that initial contents of pg_conversion system catalog are created
in the initdb process. So doing initdb required is ideal, it's
possible to add them to your databases by hand, however. To accomplish
this:
psql -f your_postgresql_install_path/share/conversion_create.sql your_database
So I did not bump up the version in cataversion.h.
TODO:
Add more conversion procs
Add [CASCADE|RESTRICT] to DROP CONVERSION
Add tuples to pg_depend
Add regression tests
Write docs
Add SQL99 CONVERT command?

Here's a patch to fix the binary string doc errors.
Joe Conway
to build dependencies for rules, constraint expressions, and default
expressions. Repair some problems in the original design of
recursiveDeletion() exposed by more complex dependency sets. Fix
regression tests that were deleting things in illegal sequences.
UNIQUE and DISTINCT predicates are both listed as implemented -- AFAIK,
neither is.
I also included another trivial patch which adds the default location
of the DSSSL stylesheets on my system (Debian unstable, docbook-dsssl
1.76) to the list of paths that configure looks for.
