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. ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
