key is the only thing pairing a website copy with the module view it came
from. A copy whose key matches nothing is never paired, so it never receives
the new inherit_id, never changes shape, and never joins a view combination.
Renaming the key is therefore enough to take it out of the way:
UPDATE ir_ui_view SET key = '<prefix>.' || key, active = false
active = false alone would NOT work: an inactive copy keeping the same key
still shadows the module view. Nothing is deleted either, so inherit_id
ondelete='restrict' and the website_page foreign keys are never touched, and
the old arch stays in database as a readable archive. --restore undoes it.
Written in plain psql on purpose: it runs on a database not yet migrated,
where starting an Odoo shell of the target version is not guaranteed. It is a
systematic step driven by the detector, valid for every bump, so it lives in
the loop rather than in a per-version fix_migration file.
Offered rather than forced, since those copies carry real customizations.
Verified on a throwaway copy: dry-run writes nothing; apply renames the key and
deactivates while keeping the 4058-char arch; a second apply is a no-op;
restore returns the row to its exact initial state.
