I’m working on my first cloud service, which will be backed by a postgresql database. Currently I only have a single customer, but of course I want to design with the possibility of multiple customers in mind. In that vein, I’m wondering what is “typical” in terms of designing the DB structure to make sure that one customer doesn’t “accidentally" get data for another customer? At the moment I am leaning towards giving each customer their own set of tables, with a unique prefix for each. This would provide a “hard” separation for the data,
^^^^^^^^^^^^ I think that is called a schema:)
Ok. That’s probably an option. Although it looks from a cursory perusal that for that to work, I would have to have separate DB users with different permissions. Which would be fine, except that I don’t have permissions to create users.
Or set up a separate database for each in the cluster.
Same as above - no permissions.
At the moment, I am running on Heroku, which gives me a postgresql database, but not full control over the cluster. I may need to move to something more robust, if having completely separate databases is the best option. I was hoping to avoid SysAdmin stuff as much as possible, and focus on the software side, but obviously some sys admin is required.

Wasn’t aware of that. I *did* mention this is my first cloud project. Done plenty of DB/web/application development, but not cloud/multi-customer. Thanks for the pointer. ---

but would also increase maintenance efforts, as if I needed to add a field I would have to add it to every table. On the other hand, keeping everything in the same set of tables would mean having to be VERY careful with my SQL to make sure no customer could access another’s data.
How is this typically done?
