FRC: pg_metadata, pg_convert, pg_insert, etc

Hi to all database module maintainers, I've committed some new PostgreSQL functions and manual pages for these. pg_metadata() - get medata data pg_convert() - check and convert array accoding to metadata pg_insert()/update()/select()/delete() - does insert, etc by array. With the new function, users can do safely. <?php $db = pg_connect(); pg_insert($db, 'get_value_log', $_GET) or user_sent_malformed_data(); ?> Since, pg_insert() lookup metadata and convert array values safely used in SQL. Please take a look at API, since you or other person may implement same feature for your database in the future. And API should be consistent whenever it's possible. I can change API if it's before PHP 4.3.0. Thank you. -- Yasuo Ohgaki
