- full support for IW (ISO week) and vice versa conversion for IW too
(the to_char 'week' support is now complete and I hope correct).
Thomas, I use for IW code from timestamp.c, for this I create separate
function date2isoweek() from original 'case DTK_WEEK:' code in the
timestamp_part(). I mean will better use one code for same feature in
date_part() and in to_char(). The isoweek2date() is added to timestamp.c
too. Right?
IMHO in 7.1 will all to_char's features complete. It is cca 41 templates
for date/time and cca 21 for numbers.
* to_ascii:
- gcc, is it correct now? :-)
In the patch is documentation for to_char's IW and for to_ascii().

I did not force. I marked numeric as compressable-but-not-move-off-able,
partly to test that storage mode and partly because I've got doubts
that numerics are large enough to need external storage.

one of updating the whole text datatype, but there are so dang many
calls of these two routines that it seems worth a separate commit.

WARNING: This is actually broken - we have self-deadlocks
due to concurrent changes in buffer management.
Vadim and me are working on it.

Now the to_timestamp() support WW,W,J,SSSS,DDD conversion from strings and
the am/pm bug is fixed, the to_char() use week-of-year (WW) full compatible
with Oracle.
This patch update relevant regress-tests and docs too.

we'll get there one day.
Use `cat' to create aclocal.m4, not `aclocal'. Some people don't
have automake installed.
Only run the autoconf rule in the top-level GNUmakefile if the
invoker specified `make configure', don't run it automatically
because of CVS timestamp skew.

functions that take pass-by-value datatypes. Should be ready for
port testing ...

to_char. I don't know about the rest of the world, but the "standard" in
Australia is the following:
1st, 2nd, 3rd, 4th - 9th
10th - 19th
21st, 22nd, 23rd, 24th - 29th (similarly for 30s - 90s)
110th - 119th (and for all "teens")
121st, 122nd, 123rd, 124th - 129th
I think you see the trend. The current code works fine except that it
produces:
111st, 112nd, 113rd, 114th - 119th
211st, 212nd, 213rd, 214th - 219th ... and so on.
Without knowing anything about what's supported (and what isn't) in the usual
I18N libraries, should this type of behaviour be defined within the locales?

inputs have been converted to newstyle. This should go a long way towards
fixing our portability problems with platforms where char and short
parameters are passed differently from int-width parameters. Still
more to do for the Alpha port however.

small changes in formatting.c code (better memory usage ...etc.) and
better
to_char's cache (will fastly for more to_char()s in one query).
(It is probably end of to_char() development in 7.0 cycle.)

the to_char() source code is large, here are regression tests for
numeric/timestamp/int8 part. It is probably enough test for formatting
code in the formatting.c module. The others (float4/float8/int4) types
share this formatting code and eventual bugs for these types aren't
few probable.
Patch fix timestamp_to_char() for infinity/invalid timestamp too.

Transform datetime and timespan into timestamp and interval.
Deprecate datetime and timespan, though translate to new types in gram.y.
Transform all datetime and timespan catalog entries into new types.
Make "INTERVAL" reserved word allowed as a column identifier in gram.y.
Remove dt.h, dt.c files, and retarget datetime.h, datetime.c as utility
routines for all date/time types.
date.{h,c} now deals with date, time types.
timestamp.{h,c} now deals with timestamp, interval types.
nabstime.{h,c} now deals with abstime, reltime, tinterval types.
Make NUMERIC a known native type for purposes of type coersion. Not tested.

The PostgreSQL's to_char() is very compatible with Oracle's to_char
now. I hope that to_char's 3000 rows of source is without bugs, but
will good if anyone test it, for me it works very well :-)

family functions. Contain:
conversion from a datetype to formatted text:
to_char( datetime, text)
to_char( timestamp, text)
to_char( int4, text)
to_char( int8, text)
to_char( float4, text)
to_char( float8, text)
to_char( numeric, text)
vice versa:
to_date ( text, text)
to_datetime ( text, text)
to_timestamp ( text, text)
to_number ( text, text) (convert to numeric)
PostgreSQL to_char is very compatible with Oracle's to_char(), but not
total exactly (now). Small differentions are in number formating. It will
fix in next to_char() version.
! If will this patch aplly to the main tree, must be delete the current
to_char version in contrib (directory "dateformat" and note in contrib's
README), this patch not erase it (sorry Bruce).
The patch patching files:
doc/src/sgml/func.sgml
^^^^^^^^
Hmm, I'm not sure if my English... :( Check it anyone (volunteer)?
Thomas, it is right? SGML is not my primary lang and compile
the current PG docs tree is very happy job (hard variables setting in
docs/sgml/Makefile --> HSTYLE= /home/users/t/thomas/.... :-)
What add any definition to global configure.in and set Makefiles in docs
tree via ./configure?
src/backend/utils/adt/Makefile
src/backend/utils/adt/formatting.c
src/include/catalog/pg_proc.h
src/include/utils/formatting.h
