/*
* ThrowErrorData --- report an error described by an ErrorData structure
*
* This is somewhat like ReThrowError, but it allows elevels besides ERROR,
* and the boolean flags such as output_to_server are computed via the
* default rules rather than being copied from the given ErrorData.
* This is primarily used to re-report errors originally reported by
* background worker processes and then propagated (with or without
* modification) to the backend responsible for them.
* This function should be called on an ErrorData structure that isn't stored
* on the errordata stack and hasn't been processed yet. It will call
* errstart() and errfinish() as needed, so those should not have already been
* called.
*
* ThrowErrorData() is useful for handling soft errors. It's also useful for
* re-reporting errors originally reported by background worker processes and
* then propagated (with or without modification) to the backend responsible
* for them.
