Hi all,
i have a litte problem using indexes with datatypes int and int8.
i have a table
test:id1 int, id2 int8
if have to indexes:
index_test_1:
--------+---------id1 | integer
btree
index_test_2:
--------+--------id2 | bigint
btree
If i do any explains i got the following:
db_nmkm3=# explain select * from test where id1=1;
Index Scan using index_test_1 on test (cost=0.00..3.01 rows=1 width=12)
db_nmkm3=# explain select * from test where id2=1;
Seq Scan on test (cost=0.00..20.55 rows=1 width=12)
db_nmkm3=# explain select * from test where id2=1::int8;
Index Scan using index_test_2 on test (cost=0.00..3.01 rows=1 width=12)
Can somebody explain me whats wrong with me or my indexes?
