be able to apply against what you just committed. It rolls soundex into
fuzzystrmatch.

Remove soundex/metaphone and merge into fuzzystrmatch.

metaphone() in a contrib. There seem to be a fair number of different
approaches to both of these algorithms. I used the simplest case for
levenshtein which has a cost  of 1 for any character insertion, deletion, or
substitution. For metaphone, I adapted the same code from CPAN that the PHP
folks did.

A couple of questions:
1. Does it make sense to fold the soundex contrib together with this one?

2. I was debating trying to add multibyte support to levenshtein (it would
make no sense at all for metaphone), but a quick search through the contrib
directory found no hits on the word MULTIBYTE. Should worry about adding
multibyte support to levenshtein()?

a PostgreSQL user-defined function.  The Metaphone system is a method of
matching similar sounding names (or any words) to the same code.

Metaphone was invented by Lawrence Philips as an improvement to the popular
name-hashing routine, Soundex.

This metaphone code is from Michael Kuhn, and is detailed at
   http://aspell.sourceforge.net/metaphone/metaphone-kuhn.txt

Could do with more testing, but it works in the simple cases.

contrib/init.d start script.  Place into more aptly named directory.  Maybe
we could add scripts for other platforms here later.

check one last time for any erros ...

ignore his too

and this time?

try this again ...

okay, this appears to work ...

onlly changes aer adding some white space ...

revise ODBC "installation instructions"; update some other outdated
documentation; update contrib documentation

prepared for dirtribution (it needs a little changes). I can change and work
on this, but I need motivation :-)

And Peter, I know and I agree that standard PG tree is not good space for
all interfaces and for all tools based on PG, but LO is PG feature and we
haven't backup tool for LO.

estimation operators.  See contrib/likeplanning/README for info.

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

TO_DATE()
and PgSQL extension FROM_CHAR().

TO_CHAR() routine allow formating text output with a datetime values:

        SELECT TO_CHAR('now'::datetime, '"Now is: "HH24:MI:SS');
        to_char
        ----------------
        Now is: 21:04:10

FROM_CHAR() routine allow convert text to a datetime:

        SELECT FROM_CHAR('September 1999 10:20:30', 'FMMonth YYYY
HH:MI:SS');
        from_char
        -----------------------------
        Wed Sep 01 10:20:30 1999 CEST

TO_DATE() is equal with FROM_CHAR(), but output a Date only:

        SELECT TO_DATE('September 1999 10:20:30', 'FMMonth YYYY
HH:MI:SS');
        to_date
        ----------
        09-01-1999


In attache is compressed dir for the contrib. All is prepared, but I'am
not
sure if Makefile is good (probably yes).

Comments & suggestions ?


Thomas, thank you for your good advices.

                                                        Karel
