Thanks. A question though: how does "make check" or "make installcheck"
chooses between the *.out and its different *_N.out incarnations?
I couldn't find traces of prepared_xacts_1.out in any file saying "this
is the one to be used in this-and-this" configuration. Does the procedure
check against all versions and the least different one is reported?
