Index scan on CIDR field ?

От

Дата:
I created index on CIDR field on table with about 1 000 000 rows, made 
'vacuum analyze', but exlain told me that sequental scan is doneon query like that SELECT * FROM table WHERE
ipaddr='212.129.92.1'
 I'm using PostgreSQL 6.5.1. I need a index scan. Do I miss something ?

did you create an index?

create index_name on tablename (row_name);

you would also get one automatically if when you created the table you'd
made that row a PRIMARY KEY
