I tried an Index Scan but I kept on getting Seq Scan. Do you know why ? What do I need to do to get my query to use index scan (I tried to turn it on by doing SET ENABLE_indexscan = on; but it didn't work)
create table test (test_col text); create index test_index on test (test_col); insert into test values ('abc.xyz'); insert into test values ('abcxyz'); insert into test values ('abc/xyz');
explain select * from test where test_col like 'abc/%';
NOTICE: QUERY PLAN:
Seq Scan on test (cost=0.00..22.50 rows=10 width=12)
Another question:
Does Regex (~*) or like use table scan ?
Thanks,
Sam
