psql -E will show you the query;  that is in the FAQ.

	$ psql -E test
	psql (8.4devel)
	Type "help" for help.
	test=> \df
	********* QUERY **********
	SELECT n.nspname as "Schema",
	  p.proname as "Name",
	  pg_catalog.pg_get_function_result(p.oid) as "Result data type",
	  pg_catalog.pg_get_function_arguments(p.oid) as "Argument data types"
	FROM pg_catalog.pg_proc p
	     LEFT JOIN pg_catalog.pg_namespace n ON n.oid = p.pronamespace
	WHERE p.prorettype <> 'pg_catalog.cstring'::pg_catalog.regtype
	      AND p.proargtypes[0] IS DISTINCT FROM
	      AND NOT p.proisagg
	      AND n.nspname <> 'pg_catalog'
	  AND pg_catalog.pg_function_is_visible(p.oid)
	ORDER BY 1, 2, 4;
	                   List of functions
	 Schema | Name | Result data type | Argument data types
	(0 rows)

That is for Postgres 8.4.
