Subject: Index usage for tstzrange?

Folks,
I just noticed that if I use a tstzrange for convenience, a standard
btree index on a timestamp won't get used for it. Example:
table a (
id int,
val text,
ts timestamptz
);
index a_ts on a(ts);
SELECT * FROM a WHERE ts <@ tstzrange('2013-01-01','2013-01-01 00:10:00')
... will NOT use the index a_ts. Is this something which could be fixed
for 9.4?
