pg_result_error

(PHP 4 >= 4.2.0, PHP 5)

pg_result_error() returns any error message
associated with the result resource. Therefore,
the user has a better chance of getting the correct error message than
with pg_last_error().

The function pg_result_error_field() can give much greater
detail on result errors than pg_result_error().

Because pg_query() returns FALSE if the query fails,
you must use pg_send_query() and
pg_get_result() to get the result handle.

PostgreSQL query result resource, returned by pg_query(),
pg_query_params() or pg_execute()
(among others).

Returns a string if there is an error associated with the
result parameter, FALSE otherwise.

Example 1. pg_result_error() example

  $dbconn = pg_connect("dbname=publisher") or die("Could not connect");
 
  if (!pg_connection_busy($dbconn)) {
      pg_send_query($dbconn, "select * from doesnotexist;");
  }
 
  $res1 = pg_get_result($dbconn);
  echo pg_result_error($res1);
