This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Contract
- pgtype.Null is Status constant 1 representing SQL NULL, distinct from Undefined (0) and Present (2)
- pgtype.Text.Set and pgtype.Int4.Set with nil or typed nil pointer set status to pgtype.Null, and Get returns nil
- pgtype.Text.Value returns nil driver.Value for Null status without error, whereas Undefined status returns an error
- pgtype.Text.Scan with nil sets status to pgtype.Null
- pgtype.Text.AssignTo with Null status sets pointer-to-pointer or slice to nil, and returns an error for direct value destination
- pgtype.Text.EncodeText and EncodeBinary return nil bytes for Null status without error, whereas Undefined status returns an error
- pgtype.Text.DecodeText and DecodeBinary with nil slice set status to pgtype.Null
