Build: PHP 5.5.8 (cli) (built: Jan  9 2014 08:33:30)

Documentation for pg_result_error states:
"Returns a string if there is an error associated with the result parameter, FALSE otherwise."
but empty String ("") is returned.

Test script:

$conn = pg_pconnect("host=... port=5432 dbname=myDB user='postgres' password='...'");
pg_send_query($conn, "SELECT count(*) FROM existingTable;");
$ress = pg_get_result($conn);
$errmsg = pg_result_error($ress);
var_dump($errmsg);


Expected result:
----------------
bool(false)

Actual result:
--------------
string(0) ""
