Bug: the index on INTEGER field does not work (PG 7.1.2).
Test 1:
1) create table test_int(id int primary key);
2) insert 10000 records in table test_int with perl program (values
1,2,3,...,10000).
3) 500 times execute query
SELECT * FROM test_int WHERE id = random number
(random number puts with perl program)
4) 500 queries executes for 30 seconds
Test 2:
1) create table test_int1(id int); (i.e. without primary key)
2) insert 10000 records in table test_int1 with perl program (values
1,2,3,...,10000).
3) 500 times execute query
SELECT * FROM test_int1 WHERE id = random number
(random number puts with perl program)
4) 500 queries executes for 30 seconds too :~-( ...
P.S. For TEXT field the same operations executes for 30 and 1 seconds
correspondingly.
