Seems it should behave just like dropping a column of a table that
already has an index on it:
test=> CREATE TABLE test(x int, y int);CREATE TABLEtest=> CREATE INDEX ii ON test(y);CREATE INDEXtest=> ALTER TABLE
testDROP COLUMN y;ALTER TABLEtest=> \d test     Table "public.test" Column |  Type   |
Modifiers--------+---------+-----------x      | integer |
 

which I think means drop the index automatically.
