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.
