This function is as simple as it sounds, it returns the name of the database your are currently connected to on the handle retrieved from a pg_connect() call.

<?php
    $pgsql_conn 
pg_connect("dbname=mark host=localhost");

    if (
$pgsql_conn) {
        print 
"Successfully connected to database: " pg_dbname($pgsql_conn) .
         
" on " pg_host($pgsql_conn) . "<br/>\n";
    } else {
        print 
pg_last_error($pgsql_conn);
        exit;
    }
?>

Successfully connected to database: mark on localhost<br/>

Again this function is much more useful when you are changing which database you are connected to in your program.
