test=# create table test (a int4, b int4); CREATE TABLE test=# create index idx on test(a) where b is null; CREATE INDEX test=# \d test Table "public.test" Column | Type | Modifiers --------+---------+----------- a | integer | b | integer | Indexes: idx btree (a) WHERE (b IS NULL)
test=# alter table test drop column b; ALTER TABLE test=# \d test Table "public.test" Column | Type | Modifiers --------+---------+----------- a | integer | Indexes: idx btree (a) WHERE ("........pg.dropped.2........" IS NULL)
And this in 7.5CVS:
test=# create table test (a int4, b int4); CREATE TABLE test=# create index idx on test(a) where b is null; CREATE INDEX test=# alter table test drop column b; ALTER TABLE test=# \d test Table "public.test" Column | Type | Modifiers --------+---------+----------- a | integer |
I cannot think of any commit that fixed that??? Is it fixed in 7.3.5?
