bug on line 381 referred to non existant variable, and caused a php notice and potentially would create a misconfigured config.php database type setting.
// database
"\$config['db']['database'] = '{$db['database']}';\n\n".

+ ($db['type'] == 'pgsql' ? "\$config['db']['quote_identifiers'] = true;\n\n":'').
"\$config['db']['type'] = '{$db['type']}';\n\n".
"?>";
