 as attache of this mail is patch (to the main tree) with to_char's
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:

                     ^^^^^^^^
   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?
