i can't drop an idex

Hi everybody

I trying to drop an index,

mhc2db=> \di antic
List of relations
Schema | Name | Type | Owner | Table
--------+-------+-------+-------+-------
public | antic | index | pau |
(1 row)

but when i try to fo it I get the following error

mhc2db=> drop index antic;

ERROR: could not open relation with OID 596166

why when I do \di the table column is empty? i don't see this index in any
table but when i try to create the index again i get

mhc2db=> create index antic on h_2_dbn (aa);
ERROR: relation "antic" already exists

Some of you could tell me what is wrong?

thanks

pau
