Ask HN: Any good tools to pgdump multi tenant database?

Just joined a new company and they run a multi tenant database in postgres where each tenant is distinguished by their account ID. I'd like to be able to dump the data of a single account to my local instance to assist in debugging.

Problem is, many of the entities do not include an account ID. For example, a user can have an account ID but a user post will not but it will be tied to a user ID.

Also foreign keys aren't really implemented fully.

Are there any tools or techniques that could help make this process easier to do?
