Hello all,
I got the following result.
It's FAQ ?
drop table int2t;
create table int2t (id int2 primary key);
explain select * from int2t where id=1; NOTICE: QUERY PLAN:
Seq Scan on int2t (cost=43.00 rows=2 width=2)
explain select * from int2t where id=1::int2; NOTICE: QUERY PLAN:
Index Scan using int2t_pkey on int2t (cost=2.05 rows=2 width=2)
explain select * from int2t where id='1'; NOTICE: QUERY PLAN:
Index Scan using int2t_pkey on int2t (cost=2.05 rows=2 width=2)
Right behavior ?
Regards.
