Tom Lane 14e4e8f8c6 Avoid possible longjmp-induced logic error in PLy_trigger_build_args. 
The "pltargs" variable wasn't marked volatile, which makes it unsafe
to change its value within the PG_TRY block.  It looks like the worst
outcome would be to fail to release a refcount on Py_None during an
(improbable) error exit, which would likely go unnoticed in the field.
Still, it's a bug.  A one-liner fix could be to mark pltargs volatile,
but on the whole it seems cleaner to arrange things so that we don't
change its value within PG_TRY.

Per report from Xing Guo.  This has been there for quite awhile,
so back-patch to all supported branches.
