How can I query across multiple schemas

In my app I have split different customers into tenants by creating a schema for each customer.

How can I query all the schemas at once either using the graphical editor or the sql editor?

Is there a way to create a question where a user can choose a schema as the filter?

Hey moshe

Currently not a way.
It's an open feature request that's been around for awhile.

Thanks.

which database are you using? there are many workarounds for this

PostgresSQL
