Bruce Momjian 8096fe45ce The added aggregates are: 
(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.

PostgreSQL Database Management System
=====================================
  
This directory contains the source code distribution of the PostgreSQL
database management system.

PostgreSQL is an advanced object-relational database management system
that supports an extended subset of the SQL standard, including
transactions, foreign keys, subqueries, triggers, user-defined types
and functions.  This distribution also contains several language
bindings, including C and Tcl.

The JDBC, ODBC, C++, and Python interfaces have been moved to the PostgreSQL
Projects Web Site at http://gborg.postgresql.org for separate maintenance.
A Perl DBI/DBD driver is available from CPAN.

See the file INSTALL for instructions on how to build and install
PostgreSQL.  That file also lists supported operating systems and
hardware platforms and contains information regarding any other
software packages that are required to build or run the PostgreSQL
system.  Changes between all PostgreSQL releases are recorded in the
file HISTORY.  Copyright and license information can be found in the
file COPYRIGHT.  A comprehensive documentation set is included in this
distribution; it can be read as described in the installation
instructions.

The latest version of this software may be obtained at
ftp://ftp.postgresql.org/pub/.  For more information look at our web
site located at http://www.postgresql.org/.
