I notice this in 7.3.4:
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?
