Häufige Annahme

pgconn.PgError.Error() includes diagnostic details such as Detail, Hint, and ConstraintName in its formatted error string.

So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.

Contract

• pgconn.PgError.Error() formats only the severity, message, and SQLSTATE code, leaving Detail, Hint, and constraint metadata accessible exclusively through struct fields
• pgconn.PgError.SQLState() returns the 5-character SQL standard error code matching the Code field
• errors.As successfully extracts *pgconn.PgError when wrapped inside standard error chains
• pgconn.ErrorResponseToPgError maps wire protocol pgproto3.ErrorResponse fields into a *pgconn.PgError struct
