Verified diagnostic signature

permission denied for schema [a-zA-Z_][a-zA-Z0-9_$]*

PostgreSQL authenticated the session but the effective role lacks a required schema, table, relation, or sequence privilege for the attempted statement. Match this output from postgresql, then continue with sourced, read-only checks.

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
