Usage

CREATE INDEX ON encrypted (e eql_v2.encrypted_hmac_256_operator);

EXPLAIN ANALYZE SELECT e::jsonb FROM encrypted WHERE e = '("{\"hm\": \"abc\"}")';

 Bitmap Heap Scan on encrypted  (cost=4.20..16.65 rows=6 width=32) (actual time=0.010..0.011 rows=0 loops=1)
   Recheck Cond: (e = '("{""hm"": ""abc""}")'::eql_v2_encrypted)
   ->  Bitmap Index Scan on encrypted_e_idx  (cost=0.00..4.20 rows=6 width=0) (actual time=0.004..0.005 rows=0 loops=1)
