Yes, the client library will have to support multiple result sets too.
For example, the PHP MySQLi lib does that by providing functions to
check for and retrieve outstanding result sets in the buffer:
bool mysqli_more_results ($link)
bool mysqli_next_result ($link)
It seems like the PHP PG binding does allow (?) retrieval of multiple
result sets through pg_get_result(), but only for requests issued
asynchronously:

For MySQL I've been mostly using PHP, occasionally Java, Python and C.
