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.

- pgtype.Map
- Created
- 2026-08-18T20:56:05Z
Contract
- pgtype.NewMap initializes TypeMap with standard PostgreSQL type definitions
- pgtype.Map.TypeForName resolves standard PostgreSQL types text and int4
- pgtype.Map.TypeForOID resolves standard PostgreSQL type OIDs like bool
- pgtype.Map.Encode and pgtype.Map.Scan convert strings using text format code
- pgtype.Map.Encode and pgtype.Map.Scan convert integer values using binary format code
- pgtype.Text represents nullable text values and round-trips null and non-null states
- pgtype.Date encodes and scans date values with validity flag
- pgtype.Map.Scan returns error when scanning incompatible payload into integer target
