In v11 branch tip I get

 Append  (cost=0.00..42.39 rows=3 width=16) (actual time=0.007..0.007 rows=0 loops=1)
   ->  Seq Scan on my_table_first  (cost=0.00..42.38 rows=3 width=16) (actual time=0.006..0.006 rows=0 loops=1)
         Filter: ((my_enum = 'FIRST'::enum1) AND (my_time > now()))

and in HEAD it looks like

 Seq Scan on my_table_first  (cost=0.00..42.38 rows=3 width=16) (actual time=0.007..0.007 rows=0 loops=1)
   Filter: ((my_enum = 'FIRST'::enum1) AND (my_time > now()))

so evidently this is already fixed.
