ComputeDefaultCode looks at the current error object (not its causes) and returns: - the existing code for Error instances - SerializationFailure for roachpb retry errors that can be reported to clients - StatementCompletionUnknown for ambiguous commit errors - InternalError for assertion failures - FeatureNotSupportedError for unimplemented errors.

DangerousStatementf creates a new error for "rejected dangerous statements".

Flatten turns any error into a pgerror with fields populated.

FullError can be used when the hint and/or detail are to be tested.

GetConstraintName attempts to unwrap and find a Severity.

GetPGCode retrieves the error code for an error.

GetPGCodeInternal retrieves a code for the error.

GetSeverity attempts to unwrap and find a Severity.

HasCandidateCode returns tue iff the error or one of its causes has a candidate pg error code.

IsSQLRetryableError returns true if err is retryable.

New creates an error with a code.

Newf creates an Error with a format string.

NewInternalTrackingError instantiates an error meant for use with telemetry.ReportError directly.

NewWithDepthf creates an error with a pg code and extracts the context information at the specified depth level.

WithCandidateCode decorates the error with a candidate postgres error code.

WithConstraintName decorates the error with a severity.

WithSeverity decorates the error with a severity.

Wrap wraps an error and adds a pg error code.

Wrapf wraps an error and adds a pg error code.

WrapWithDepthf wraps an error.

WrongNumberOfPreparedStatements creates new an Error for trying to prepare a query string containing more than one statement.

DefaultSeverity is the default severity for decoding severity of errors.

InternalErrorPrefix is prepended on internal errors.

TxnRetryMsgPrefix is the prefix inserted in an error message when flattened.
