     * Find all interesting functions.  This is a bit complicated:
     *
     * 1. Always exclude aggregates; those are handled elsewhere.
     *
     * 2. Always exclude functions that are internally dependent on something
     * else, since presumably those will be created as a result of creating
     * the something else.  This currently acts only to suppress constructor
     * functions for range types.  Note this is OK only because the
     * constructors don't have any dependencies the range type doesn't have;
     * otherwise we might not get creation ordering correct.
     *
     * 3. Otherwise, we normally exclude functions in pg_catalog.  However, if
     * they're members of extensions and we are in binary-upgrade mode then
     * include them, since we want to dump extension members individually in
     * that mode.  Also, if they are used by casts or transforms then we need
     * to gather the information about them, though they won't be dumped if
     * they are built-in.  Also, in 9.6 and up, include functions in
     * pg_catalog if they have an ACL different from what's shown in
     * pg_init_privs (so we have to join to pg_init_privs; annoying).
