備考 †

* elog_start --- startup for old-style API
*
* All that we do here is stash the hidden filename/lineno/funcname
* arguments into a stack entry.
*
* We need this to be separate from elog_finish because there's no other
* portable way to deal with inserting extra arguments into the elog call.
* (If macros with variable numbers of arguments were portable, it'd be
* easy, but they aren't.)
