Hi,
I have a table that looks like this:
CREATE TABLE my_table {
id SERIAL PRIMARY KEY,
id_1 INTEGER REFERENCES tab1(id),
id_2 INTEGER REFERENCES tab2(id),
.
.
.
};
I will often be running queries that look like
SELECT * from my_table where id_1 = x and id_2 = y;
Neither id_1 or id_2 or the combination of them is unique. I expect
this table to become large over time.
What can I do to help postgres run this query efficiently (if
anything)?
Apologies if this is a "RTFM" question - I looked but did not find.
Could be I didn't look hard enough ...
thanks in advance
Daniel
