hmm. You both know the table of that name exists only as part of a
regression test, right? It'll just exist for a handful of
milliseconds during make check.
My comment about the poorly named table may have been a bit pedantic
as far as what a table in a test should be called, but I also felt a
bit of an urge to make a little bit of fun about having a table named
dual which always has just a single row. Knowing the reasons for
Oracle's naming of the table helps explain why they ended up with the
poorly named table. I didn't think that warranted us doing the same
thing, even if it's just a short-lived table inside a regression test.
