Hello
I have one problem with indexes. I have serched the mailing lists and found there a lot of info about indexes, but not
theanswer.
I done following:
create table t1 (a1 int8 not null , a2 int8 not null, a3 char (128), primary key (a1,a2));
OK
create index i1 on t1 (a1);
OK
Then i inserted about 5000 rows into into this table
Then i use EXPLAIN SELECT a1 FROM t1 WHERE a1 = 444
and the explain told me sequential scan...
I don't know where is the problem. I think that the optimizer should use index ???
(I done vacuum and nothing changed)
Thanks for help
Best regards
