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.
