    comparison functions), replacing the highly bogus bitwise array_eq.  Create
    a btree index opclass for ANYARRAY --- it is now possible to create indexes
    on array columns.
    Arrange to cache the results of catalog lookups across multiple array
    operations, instead of repeating the lookups on every call.
    Add string_to_array and array_to_string functions.
    Remove singleton_array, array_accum, array_assign, and array_subscript
    functions, since these were for proof-of-concept and not intended to become
    supported functions.
    Minor adjustments to behavior in some corner cases with empty or
    zero-dimensional arrays.

    History
    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, Perl, Python, and Tcl, as well as a JDBC
    driver.
    
    The ODBC and C++ interfaces have been moved to the PostgreSQL Projects
    Web Site at http://gborg.postgresql.org for separate maintenance.
    
    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/.
