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
----------

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.

Here is a tar file the new directories, which substitute the old ones
in contrib. Please remove the old directories array, datetime, miscutil,
string and userlock before unpacking the tar file in contrib.
Note that as the modules are now installed in lib/modules I install all
my sql code in lib/sql. In my opinion also the other contributors should
follow these rules.
test isn't that complete up to now, but I think it shows
enough of the capabilities of the module.
The Makefile assumes it is located in a directory under
pgsql/src/pl. Since it includes Makefile.global and
Makefile.port and doesn't use any own compiler/linker calls,
it should build on most of our supported platforms (I only
tested under Linux up to now). It requires flex and bison I
think. Maybe we should ship prepared gram.c etc. like for the
main parser too?

Here is some more contrib-fodder, based on TIH's IP address type,
for ISBN and ISSN identifiers (which I just happened to need to keep
track of the things in my library).
I do not know about these contributions well as I only made the binaries
to contribute to a Japanese Linux package.(I did not test them.) But I
try to make some brief introduction about the contrib directory with my
poor English. Here is a draft of README about contrib directory:
