I can reproduce this in 9.5 and HEAD on RHEL6, but 9.4 works as expected.
I presume that that points the finger at the abbreviated-keys work.

BTW, what I'm seeing in 9.5/HEAD is that all three comparison senses fail:

u8=# set enable_seqscan TO 0;
SET
u8=# select * from test where t < 'eai';
t
---
(0 rows)

u8=# select * from test where t = 'eai';
t
---
(0 rows)

u8=# select * from test where t > 'eai';
t
---
(0 rows)
