Hi to all!
Is it possible to define indexes on a column with BIGINT datatype? See
this example:
testdb=# create table a (col1 integer not null primary key);
NOTICE: CREATE TABLE/PRIMARY KEY will create implicit index 'a_pkey' for
table 'a'
CREATE
testdb=# create table b (col1 bigint not null primary key);
NOTICE: CREATE TABLE/PRIMARY KEY will create implicit index 'b_pkey' for
table 'b'
CREATE
testdb=# explain select * from a where col1=123;
NOTICE: QUERY PLAN:
Index Scan using a_pkey on a (cost=0.00..8.14 rows=10 width=4)
EXPLAIN
testdb=# explain select * from b where col1=123;
NOTICE: QUERY PLAN:
Seq Scan on b (cost=0.00..22.50 rows=10 width=8)
On table a (INTEGER datatype) the search is done using the index.
Instead on table b (BIGINT datatype) the search is always done using the
seq scan.
Is it a bug?
I use Postgresql 7.1.2 on RedHat 7.1. All the regress tests has been
completed correctely during installation.
Please, let me know as soon as possible...
