I have a table with a column titled 'passfail' that only contains either a P
for pass or an F for fail. The table name is 'one'. I created the index on
the table with:
CREATE INDEX one_passfail_idx ON one USING btree (passfail);
I then do:
VACUUM ANALYZE one;
Then I do an explain on this query:
SELECT * FROM one where passfail = 'P';
and it tells me:
Seq Scan on one (cost=0.00..263.02 rows=5613 width=56)
Shouldn't it tell me
Index Scan using one_passfail_idx on one?
Why isn't it using the index? Thanks, I appreciate the help!
