-- Hand-written, like 0005, because drizzle-kit cannot express this safely.

-- Two traps live in these three lines.
--
-- First, `ALTER TYPE ... ADD VALUE` could not run inside a transaction block
-- before Postgres 12, and the drizzle migrator wraps every migration in one.
-- PIG targets Postgres 16, where it is permitted; what remains forbidden even
-- on 16 is *using* the new value in the same transaction, so nothing here may
-- reference 'viewer' — no backfill, no default change, no CHECK. Adding one
-- later means its own migration.
--
-- Second, `BEFORE 'member'` is not cosmetic. `viewer` outranks nobody, and the
-- enum's sort order is what `ORDER BY role` and any future comparison would
-- use. Appending it to the end would silently make the least privileged role
-- sort as the most senior.
ALTER TYPE "public"."pig_team_role" ADD VALUE IF NOT EXISTS 'viewer' BEFORE 'member';
