Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. pgconn.ParseConfig parses PostgreSQL connection URI into Config
  2. pgconn.ParseConfig returns an error for invalid connection strings
  3. pgconn.NewCommandTag parses INSERT tag and reports correct predicate and row count
  4. pgconn.CommandTag predicates correctly identify UPDATE, DELETE, and SELECT tags
  5. pgconn.PgError exposes structured PostgreSQL error attributes
  6. pgconn.PgError.SQLState returns SQLSTATE code
  7. pgconn.PgError unwraps cleanly via errors.As from wrapped error chains
  8. pgconn.PgError.Error formats message and SQLSTATE
