Sample
verify pgtype.Interval parsing, value conversion, and scanning in pkg:golang/github.com/jackc/pgx/v5@v5.10.0

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.

Contract
- pgtype.Interval.Scan parses PostgreSQL formatted interval strings into Months, Days, and Microseconds components
- pgtype.Interval.Scan handles nil input by setting Valid to false to represent SQL NULL
- pgtype.Interval.Value returns formatted driver string for valid intervals and nil for invalid intervals
- pgtype.Interval.IntervalValue returns underlying Interval value and nil error for valid interval
- pgtype.Interval.ScanInterval copies interval properties from source to destination instance
- pgtype.Interval.Scan returns error for invalid interval string representations
- Sample helper functions parse, format, clone, and extract interval values
