A data table backed by the instance database resolved to exactly one Postgres connection,
`custom_instance_user`, for everyone who could reach it at all. There was no way to say
this job reads, that one writes, this one never sees the salaries table.
A data table role is now a real Postgres login on the cluster, defined once for the
instance by a superadmin and named exactly as they named it. A script that declares
`-- role analytics` connects as `analytics`, and Postgres decides what it may touch —
grants are ordinary SQL. Windmill answers only "may this caller ask for this role", from
the tenant lists on the data table entry: `u/alice`, `g/analysts`, `f/finance` or `*`.
A data table with no `permissions` block behaves exactly as before.
Everything that opens a connection on someone's behalf goes through one chokepoint,
`get_datatable_resource_from_db`, which takes the identity explicitly and fails closed when
there is none. The role logs in as itself — never `SET ROLE`, which a script could
`RESET ROLE` its way out of.
A fork's data table entry becomes a pointer at the workspace that governs it rather than a
copy of it. The settings clone used to hand a fork a byte-identical entry naming the
parent's database, which a fork admin could edit to grant themselves `admin` there; a
pointer has nothing local to edit, and its tenants are evaluated as a member of the
governing workspace, by email. `permissions` is stripped from the workspace export and
ignored on import: tenants name principals of one workspace, and a settings push is not
where an access decision should be made.
Operations that see the whole database whatever the roles grant stay with the governing
workspace's admins: editing the roles, a migration that declares none, and opening a
replication stream for a Postgres trigger or capture.

Attach custom-instance datatables in the DuckDB executor through a DuckDB
secret instead of an inline connection string, and route postgres triggers on
custom-instance datatables through a dedicated custom_instance_replication_user
role (with its own auto-generated password in global_settings). Normalize
custom_instance_user attributes on server boot.
