- * formatting.c
- *
- * $Header: /cvsroot/pgsql/src/backend/utils/adt/formatting.c,v 1.53 2002/04/21 19:48:12 thomas Exp $
- *
- *
- *	 Portions Copyright (c) 1999-2000, PostgreSQL Global Development Group
- *
- *
- *	 TO_CHAR(); TO_TIMESTAMP(); TO_DATE(); TO_NUMBER();
- *
- *	 The PostgreSQL routines for a timestamp/int/float/numeric formatting,
- *	 inspire with Oracle TO_CHAR() / TO_DATE() / TO_NUMBER() routines.
- *
- *
- *	 Cache & Memory:
- *	Routines use (itself) internal cache for format pictures.
- *
- *	The cache uses a static buffers and is persistent across transactions.
- *	If format-picture is bigger than cache buffer, parser is called always.
- *
- *	 NOTE for Number version:
- *	All in this version is implemented as keywords ( => not used
- *	suffixes), because a format picture is for *one* item (number)
- *	only. It not is as a timestamp version, where each keyword (can)
- *	has suffix.
- *
- *	 NOTE for Timestamp routines:
- *	In this module the POSIX 'struct tm' type is *not* used, but rather
- *	PgSQL type, which has tm_mon based on one (*non* zero) and
- *	year *not* based on 1900, but is used full year number.
- *	Module supports AD / BC / AM / PM.
- *
- *	Supported types for to_char():
- *
- *		Timestamp, Numeric, int4, int8, float4, float8
- *
- *	Supported types for reverse conversion:
- *
- *		Timestamp	- to_timestamp()
- *		Date		- to_date()
- *		Numeric		- to_number()
- *
- *
- *	Karel Zak
- *
- * TODO
- *	- better number building (formatting) / parsing, now it isn't
- *		  ideal code
- *	- use Assert()
- *	- add support for abstime
- *	- add support for roman number to standard number conversion
- *	- add support for number spelling
- *	- add support for string to string formatting (we must be better
- *	  than Oracle :-),
- *		to_char('Hello', 'X X X X X') -> 'H e l l o'
