I don't have/use PG, so unfortunately I can't do it myself.

Description:
------------
Impossible to retrieve properly binary data from a binary field in
Postgresql.
It should work with the SQL BINARY CURSOR OPTION in Postgres, but data
returned is truncated.

Reproduce code:
---------------
CREATE TABLE test(binfield byteA) ;
INSERT INTO test VALUES (decode('0103AA000812','hex'));

//First try
$data =pg_query("SELECT binfield FROM test");
$res=pg_fetch_result($data,0);
echo $res;  // =>"\001\003\252\000\010\022"
echo bin2hex(pg_unescape_bytea($res)); //=> "0103aa000812"
//By default, Potsgresql returns binary field values as strings, so we
need to unescape them to restore original binary data. Tedious.
Performance issue here.

//second try
$sql="BEGIN;DECLARE mycursor BINARY CURSOR FOR SELECT binfield FROM
test;fetch all in mycursor;";
//the BINARY CURSOR option forces PostgreSQ to return binary data
$data =pg_query($sql);
$res=pg_fetch_result($data,0); 
echo strlen($res);  //=> 3
echo bin2hex($res); //=> 0103aa

//BUG : data returned is truncated, as soon as a "00" byte is
encountered, 

Expected result:
----------------
i am expecting to retrieve full binary content
