Likely causes

What usually produces this signal

  1. The role lacks USAGE on the object schema
  2. The role lacks the operation-specific privilege on the table, view, or sequence
  3. Role membership is absent, not inherited, or not activated with SET ROLE
  4. Default privileges were configured for a different object-creating role
  5. Row-level security or an ownership boundary is being confused with an object ACL
