-- Reference schema for the lookup direct backend: PostgreSQL (tables only, no stored procedures). Use with lookup.Config{Mode: lookup.ModeDirect}.
-- Do not combine with the procedure schema (database_schema.sql): that schema stores credential ids as bytea and
-- list columns as text[], this one stores base64 / JSON text which is what the direct backend reads and writes.
-- Table and column names are the lookup.DefaultSchema defaults, override them with lookup.Config.Schema.
-- Generated by the project, edit freely for your deployment (types, collations, extra columns).

--   password: bcrypt hash (nullable for OAuth2 users), legacy cleartext is accepted at login
