Functions

func ErrFormat

func ErrFormat(str string, args ...interface{}) error

func ErrFormatStr

func ErrFormatStr(str string, args ...interface{}) error

func SafeToRetry

func SafeToRetry(err error) bool

SafeToRetry checks if the err is guaranteed to have occurred before sending any data to the server.

func Timeout

func Timeout(err error) bool

Timeout checks if err was was caused by a timeout. To be specific, it is true if err was caused within pgconn by a context.Canceled, context.DeadlineExceeded or an implementer of net.Error where Timeout() is true.

PgError represents an error reported by the PostgreSQL server. See http://www.postgresql.org/docs/11/static/protocol-error-fields.html for detailed field description.

func ErrorResponseToPgError

func ErrorResponseToPgError(msg *pgproto3.ErrorResponse) *PgError

ErrorResponseToPgError converts a wire protocol error message to a *PgError.

func (*PgError) Error

func (pe *PgError) Error() string

func (*PgError) SQLState

func (pe *PgError) SQLState() string

SQLState returns the SQLState of the error.
