範例 1. Getting table metadata
`<?php $dbconn = pg_connect("dbname=publisher") or die("Could not connect"); $meta = pg_meta_data($dbconn, 'authors'); if (is_array($meta)) { echo '<pre>'; var_dump($meta); echo '</pre>'; } ?>`
The above example will output:
    array(3) {
    ["author"]=>
    array(5) {
      ["num"]=>
      int(1)
      ["type"]=>
      string(7) "varchar"
      ["len"]=>
      int(-1)
      ["not null"]=>
      bool(false)
      ["has default"]=>
      bool(false)
    }
    ["year"]=>
    array(5) {
      ["num"]=>
      int(2)
      ["type"]=>
      string(4) "int2"
      ["len"]=>
      int(2)
      ["not null"]=>
      bool(false)
      ["has default"]=>
      bool(false)
    }
    ["title"]=>
    array(5) {
      ["num"]=>
      int(3)
      ["type"]=>
      string(7) "varchar"
