lowerstr() and lowerstr_with_len() in ts_locale.c do the same thing as str_tolower() that the rest of the system uses, except that the former don't use the common locale provider framework but instead use the global libc locale settings. This patch replaces uses of lowerstr*() with str_tolower(..., DEFAULT_COLLATION_OID). For instances that use a libc locale globally, this will result in exactly the same behavior. For instances that use other locale providers, you now get consistent behavior and are no longer dependent on the libc locale settings (for this case; there are others). Most uses of these functions are for processing dictionary and configuration files. In those cases, using the default collation seems appropriate. At least we don't have a more specific collation available. But the code in contrib/pg_trgm should really depend on the collation of the columns being processed. This is not done here, this can be done in a separate patch. (You can probably construct some edge cases where this change would create some locale-related upgrade incompatibility, for example if before you used a combination of ICU and a differently-behaving libc locale. We can document this in the release notes, but I don't think there is anything more we can do about this.)
