Subject: Enable routine running of regex.linux.utf8 regression test.
X-Git-Tag: REL_15_BETA1~965
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=72a3ebf235b52fdb715214027026f66a0ad7da4d;p=thirdparty%2Fpostgresql.git

Enable routine running of regex.linux.utf8 regression test.

Up to now this has just sat there as a test you could invoke via
EXTRA_TESTS, which of course nobody does.  I'm feeling encouraged
because c2e8bd275 hasn't yet broke anything, so let's try making this
run with a suitable guard condition (similar to collate.linux.utf8).
