Lets say I have a Postgresql table where I store uploaded data for all users, identified by user_id column. Is it possible to run a query to measure the storage a user is consuming?
Not really. You could get the size of the whole table with pg_relation_size() and then estimate a user's share by seeing what % of rows have their user-id.
If it's the sort of thing you'll be checking constantly, then I'd keep a summary table up-to-date using triggers instead.
Oh - if you're going to be asking questions regularly then you'll probably get more answers if you have a valid email address.
