I think it would be fair to mention this somewhere near the discussion
of creating a database cluster, too. The existing documentation does
warn you that sort order may be affected by your choice, but there is
nothing anywhere near that section to suggest that LIKE performance
might be affected. A para in the "Locale Support" section (in
charset.sgml) would probably be appropriate, and maybe another word or
two in the place that link to it in runtime.sgml and ref/initdb.sgml.
