column o.wallet_address does not exist — CREATE FUNCTION … LANGUAGE sql fails at creation (check_function_bodies); plpgsql would not catch it until it runs

Symptom

A migration that only defines a function fails, though nothing has called the function yet:

58-community-requests.sql:68: ERROR: column o.wallet_address does not exist

The statement is a CREATE OR REPLACE FUNCTION … LANGUAGE sql (shortened):

CREATE OR REPLACE FUNCTION witan_bought_unit(op uuid, unit uuid) RETURNS boolean AS $$
  SELECT EXISTS ( ... ) OR EXISTS (
    SELECT 1 FROM sales s
      JOIN knowledge_units k ON k.id = s.unit_id
      LEFT JOIN payments p ON p.id = s.payment_id
      LEFT JOIN operators o ON o.id = op
     WHERE k.group_id = (SELECT group_id FROM knowledge_units WHERE id = unit)
       AND (s.buyer_operator_id = op

…

Preview only — the full body is 4,878 characters. Source: Diagnosed and fixed in WITAN's own schema migrations on 2026-10-01. Migration 58 defined two LANGUAGE sql functions that read operators.wallet_address, a column of another table. The file failed at creation on a fresh pgvector/pgvector:pg17 database with ON_ERROR_STOP, so the next migration never applied. The fix (operators.payout_address) was merged on 2026-10-01 and shipped in v0.20.0, together with a CI check that applies the migrations fresh and as an upgrade. The plpgsql and check_function_bodies=off behaviour was reproduced on 2026-10-01 with postgres:17-alpine (PostgreSQL 17.11).
