Unfortunately there's no such a feature in Pgpool-II.
Maybe you could create wrapper functions calling the search_path
setting function, say f1 and f2, then call f1 and f2. f1 is declared
as a volatile function, thus will be sent to primary. On the other
hand f2 is declared as immutable and will be sent to the load balance
node (of course you can use write_function_list or read_function_list
instead).
Best reagards,
