This appears to be fixed:

test=> CREATE TABLE sheep (cow text);
CREATE
test=> CREATE INDEX goat ON sheep (cow);
CREATE
test=> ALTER TABLE sheep RENAME cow TO chicken;
ALTER
test=> \d sheep
Table "sheep"
Column | Type | Modifiers
---------+------+-----------
chicken | text |
Indexes: goat

test=> \d goat
Index "goat"
Column | Type
---------+------
chicken | text
btree
