Well, it would work on any platform that reports high Unicode letters as letters. The problem for putting this into the regular regression tests is that the generic tests don't even assume UTF8 encoding, let alone a Unicode-ish locale. > Since we're now de facto maintainers of this regexp library, and our > version could be used somewhere else than PostgreSQL too, it would > actually be nice to have a regression suite that's independent from the > pg_regress infrastructure, and wouldn't need a server to run. If anyone ever really picks up the challenge of making the regexp library a standalone project, I think one of the first orders of business would be to pull out the Tcl project's regexp-related regression tests. There's a pretty extensive set of tests written by Henry Spencer himself, and more that they added over the years; it's far more comprehensive than our tests. (I've looked at stealing that test set in toto, but it requires some debug APIs that we don't expose in SQL, and probably don't want to.) In any case, this is getting very far afield from the current patch. I'm willing to add a regexp.linux.ut8.sql test file if you think it's important to have some canned tests that exercise this new code, but otherwise I don't see any near-term solution. regards, tom lane -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
