Bruce Momjian 1c5aec60bb I finish devel. of Oracle compatible DateTime routines TO_CHAR(),
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).

                                                        Karel
