I can't bring myself to commit that, it's not really in the spirit of
this data integrity feature, and it's not our business to second guess
the relationship between different locale naming schemes through fuzzy
logic. Instead, I propose to just neuter the feature if Windows
decides it can't understand a locale names that it gave us. It should
still work fine with something like initdb --lc-collate=en-US. Here's
an untested patch. Thoughts?
