Although we haven't been terribly consistent about it, some of our macros
address this problem by using local variable names with a leading and/or
trailing underscore, or otherwise making them names you'd be quite
unlikely to use in normal code.  I suggest doing something similar
here.  (Wouldn't be a bad idea to make PG_TRY's variables follow suit.)
