Sorry, I've not actually looked at that patch yet. I felt I should
push on Andres' CTAS patch first, since that's blocking progress on
the command triggers patch.

If they rely on having python, that's a 100% guaranteed rejection
in my opinion. It's difficult enough to sell people on incremental
additions of perl dependencies to the build/test process. Bringing
in an entire new scripting language seems like a nonstarter.
I suppose we could commit such a thing as an appendage that doesn't
get run in standard builds, but then I see little point in it at all.
Tests that don't get run regularly are next door to useless.
Is there a really strong reason why adequate regression testing isn't
possible in a plain-vanilla pg_regress script? A quick look at the
script says that it's just doing some SQL commands and then checking the
results of queries on the pg_stat_statements views. Admittedly the
output would be bulkier in pg_regress, which would mean that we'd not
likely want several hundred test cases. But IMO the objective of a
regression test is not to memorialize every single case the code author
thought about during development. ISTM it would not take very many
cases to have reasonable code coverage.
