This is a slightly stripped down version from our internal bug tracker. The point of posting this publicly is part FYI, part peer review. I'm hoping someone can look at this, disagree, and tell me all the downsides of using the C locale or point out things I've misunderstood. The Recommendations section in particular is contextualized by our database serving a SaaS product for users from many different locales, thus making locale a render level concern. YMMV, caveat emptor, etc.

Collation defines the character ordering for textual data. For Postgres, https://www.postgresql.org/docs/current/static/locale.html:

The locale settings influence the following SQL features:

• Sort order in queries using ORDER BY or the standard comparison operators on textual data
• The upper, lower, and initcap functions

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.
