Hi!
is this OK.
CREATE TABLE test (
id int primary key,
name varchar(255),
parent varchar(32)
);
If i write
explain select * from test where id=1;
This is output of 1st table:
Index Scan using test_pkey on test (cost=0.00..4.82 rows=1 width=183)
but the i create index on parent like this
create index tt on test (parent);
And when i execute query
explain select * from test where parent = '1';
Seq Scan on test (cost=0.00..1.07 rows=1 width=17)
Why i there no index scan if i create index. I also run
vacuum on this table.
both queryes return only 1 row.
