Extends public.language_code with the Euskera (Basque, ISO 639-1) label. Plan §20.1 was written against a CHECK-constraint mental model; the actual gate is the ENUM from migration 001, so the right primitive is ALTER TYPE … ADD VALUE. End-user contract is identical — 'eu' accepted, 'fr' rejected — and rejection surfaces as the canonical 22P02 invalid_text_representation error. pgTAP `supabase/tests/020_users_language_eu.sql` (5 assertions, LANG-EU- T01..T05) pins both ends: ENUM membership and UPDATE round-trip on Ana. Hand-curated database.ts widened to `'en' | 'es' | 'eu'`. The supabase CLI isn't on this host, so db-types regen is the manual edit per the recipe's fallback path.

-- pgTAP: `eu` accepted in public.language_code ENUM (Fase 20.1).
|
|
-- Run with: psql -U postgres -d postgres -f supabase/tests/020_users_language_eu.sql
|
|
--
|
|
-- Migration 028 extends the `public.language_code` ENUM with 'eu'. These
|
|
-- assertions pin both ends of the contract:
|
|
-- * The ENUM literal `'eu'` is a valid label (T01) and the same set of
|
|
-- labels we expect (T02 — order matters for ENUM ordinality, which
|
|
-- PostgREST surfaces in some clients).
|
|
-- * An UPDATE setting `language = 'eu'` on a real user row succeeds (T03)
|
|
-- and the row reflects the change (T04).
|
|
-- * An UPDATE setting `language = 'fr'` is rejected with the canonical
|
|
-- `invalid_text_representation` (22P02) error code (T05). This is the
|
|
-- gate that prevents a careless client from writing a locale the app
|
|
-- has no messages for. Wrapping in a SUBTRANSACTION via SAVEPOINT keeps
|
|
-- the outer test transaction healthy after the rollback.
|
|
--
|
|
-- The seed user `Ana` (id 11111111-…) is the fixture. We restore her
|
|
-- language to 'es' at the end so this file is safe to re-run.
