Row & column level permissions

[kgodey]

We'd like to support giving users access to a subset of tables – either only specific columns, or specific rows (based on the data in the row), or both.

We'd probably use Postgres row-level security for this.

If you'd like us to build this feature, please comment below with more details about how you plan to use this functionality.

Mathesar now uses Postgres permissions (in our latest test build), so this can be set up at the database layer and is reflected in the UI. I'll leave this open until we set up a UI for it.
