Обсуждение: What is faster?

I have a short table (10 records) with a primary key column.

What primary key column data type will make search faster: int2 or char?
What about char(n) n=2,3...?
I'm looking for speed, as that search is very frequent.

Thanks,

Mihai Gheorghiu

    With such a short table, won't a index lookup actually make your query
slower?
