Re: [HACKERS] [WIP] patch - Collation at database level

My patch should be "sort of" wrapper that will implement guts for further development (collation at column level) like catalogs, creating collations etc. When creating collation user will be able to choose which function to use (by statement STRCOLFN - not in SQL standard). In the first stage I'll implement function that will use system locales. Adding ICU or any other library won't be that big deal.

Out of curiosity, what is a "user-defined collation"? Are there SQL statements
to go around declaring what order code points should be sorted in? That seems
like it would be... quite tedious!
