You cannot specify the schema name in this command. You can change the search path for just one query by using the following code: 





<?php


pg_query($conn, "SET search_path TO myschema;");


    


$copy_to = pg_copy_to($conn, 'tablename');


    


pg_query("RESET search_path;");


?>

"It issues COPY TO SQL command internally to insert records"



I suspect this statement is incorrect, or that s/insert/retrieve/ is appropriate.
