Worth noting here that just like the COPY TO statement in PostgreSQL, '$table_name' can include a list of columns or be a select query as well.
e.g.:
$rows = pg_copy_to($db,'schema."TableName" (column1, column2, ...)';
$rows = pg_copy_to($db,'(SELECT ...)');

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

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

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;");

?>
