Also performed an initial run through of upgrading our Copyright date to
extend to 2005 ... first run here was very simple ... change everything
where: grep 1996-2004 && the word 'Copyright' ... scanned through the
generated list with 'less' first, and after, to make sure that I only
picked up the right entries ...

(1) boolean-and and boolean-or aggregates named bool_and and bool_or.
they (SHOULD;-) correspond to standard sql every and some/any aggregates.
they do not have the right name as there is a problem with
the standard and the parser for some/any. Tom also think that
the standard name is misleading because NULL are ignored.
Also add 'every' aggregate.
(2) bitwise integer aggregates named bit_and and bit_or for
int2, int4, int8 and bit types. They are not standard, but I find
them useful. I needed them once.
The patches adds:
- 2 new very short strict functions for boolean aggregates in
src/backed/utils/adt/bool.c,
src/include/utils/builtins.h and src/include/catalog/pg_proc.h
- the new aggregates declared in src/include/catalog/pg_proc.h and
src/include/catalog/pg_aggregate.h
- some documentation and validation about these new aggregates.

conversion of basic ASCII letters. Remove all uses of strcasecmp and
strncasecmp in favor of new functions pg_strcasecmp and pg_strncasecmp;
remove most but not all direct uses of toupper and tolower in favor of
pg_toupper and pg_tolower. These functions use the same notions of
case folding already developed for identifier case conversion. I left
the straight locale-based folding in place for situations where we are
just manipulating user data and not trying to match it to built-in
strings --- for example, the SQL upper() function is still locale
dependent. Perhaps this will prove not to be what's wanted, but at
the moment we can initdb and pass regression tests in Turkish locale.

terms, add some clarifications, fix some untranslatable attempts at dynamic
message building.

the bulk of the heavy lifting ...

but that was enough tedium for one day. Along the way, move the few
support routines for types xid and cid into a more logical place.

inputs have been converted to newstyle. This should go a long way towards
fixing our portability problems with platforms where char and short
parameters are passed differently from int-width parameters. Still
more to do for the Alpha port however.

Add istrue() and isfalse() routines to implement SQL3 IS TRUE and IS FALSE.
|
|
|
|
Allow true/false, yes/no, 1/0. Throw elog warning if anything else.
Allow shorter strings, so "t", "tr", "tru" and "true" match "true".
Old behavior accepted anything starting with "t" as TRUE,
everything else as FALSE.
|
|
Leave all other input values to return FALSE.
In next version, do more checking for valid inputs for both TRUE and FALSE.
|
|
rather than just 't' and 'T'. This allows yes/no and 1/0
to be interpreted as one might expect.
Clean up function declarations to use bool as the type for arguments
and return values.

indenting. Also static variable indenting.
|
|
|
|
Add comparison operators to boolean and smaller/larger operators to datetime
and timespan. Fix int4 overflow math problem in timespan comparison operators.
