binary cursor returning truncated data

[Eric Mauvière <e(dot)mauviere(at)geoclip(dot)fr>]

Hello,

 

i am trying to retrieve binary content of a bytea field (or postgis geometry field) with a binary cursor with PHP :

 

$sql="BEGIN;DECLARE mycursor BINARY CURSOR FOR SELECT shape FROM $layerName; fetch all in mycursor;"

....pg_query...

 

But my shape field shows only two bytes of data.

 

Does someone know if it is a current PHP restriction ?

 

Thanks by advance,

 

Eric
