Hmm. We don't need new infrastructure like the isolation tests do,
so another subdirectory seems like overkill. I am thinking about a new
target "installcheck-collations" in src/test/regress/GNUmakefile that
creates a UTF8-encoding database and runs a different test schedule than
the regular tests.
The problem we'd have is that there's no way (at present) to make such
a test pass on every platform. Windows has its own set of locale names
(which initdb fails to install as collations anyway) and we also have
the problem that OS X can be counted on to get UTF8 sorting wrong.
(It might be okay for case-folding though; not sure.) Possibly we could
just provide an alternate expected file for OS X, but I don't see a
decent workaround for Windows --- it would pretty much have to have its
very own test case.
Andrew, what kinds of options have we got for persuading the buildfarm
to run such tests only on a subset of platforms?
