plperlNG. Review and minor cleanup/improvements by Joe Conway. Summary of new functionality: - Shared data space and namespace. There is a new global variable %_SHARED that functions can use to store and save data between invocations of a function, or between different functions. Also, all trusted plperl function now share a common Safe container (this is an optimization, also), which they can use for storing non-lexical variables, functions, etc. - Triggers are now supported - Records can now be returned (as a hash reference) - Sets of records can now be returned (as a reference to an array of hash references). - New function spi_exec_query() provided for performing db functions or getting data from db. - Optimization for counting hash keys (Abhijit Menon-Sen) - Allow return of 'record' and 'setof record'
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/.
