Thank you for mentioning this.
Sorry, the last one accidentally contained garbage code to
intentionally raise an error. The last one names the nodes as
such like '001_master_24f8'. Maybe prefixing "tmp_" would be

This was a very small patch made on the old, uncommited
patches. I remade the patch and split it into two parts.
Changes of PostmasterNode.pm and TestLib.pm to add some
features and change a behavior.
This is rather a example usage of 0001- patch (except for
stderr stuff). 00n_xxx test leaves temporary directories with
the names of 00n_(master|standby)_XXXX on failure. If this is
considered reasonable, I'll make same patches for the other
