I have experienced the following problem, maybe they are related:
I create a table with
create table test (id int, name char(10));
then I create an index on it with
create index test_idx on test (id);
After populating my table, the query
select id from test where id='1';
uses index scan.
However when I only create the index AFTER inserting rows into the table,
the index is not being used for the evaluation,
even if I run vacuum / vaccum analyze on test;
I would also appreciate some help with this.
Thank you,
Norbert
