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. pgtype.NewMap initializes TypeMap with standard PostgreSQL type definitions
  2. pgtype.Map.TypeForName resolves standard PostgreSQL types text and int4
  3. pgtype.Map.TypeForOID resolves standard PostgreSQL type OIDs like bool
  4. pgtype.Map.Encode and pgtype.Map.Scan convert strings using text format code
  5. pgtype.Map.Encode and pgtype.Map.Scan convert integer values using binary format code
  6. pgtype.Text represents nullable text values and round-trips null and non-null states
  7. pgtype.Date encodes and scans date values with validity flag
  8. pgtype.Map.Scan returns error when scanning incompatible payload into integer target
