The PostgreSQL documentation leaves a lot to be desired (just sayin' 😼 ). To start with, there is only one encoding for a particular database, so C and C.UTF-8 in your UTF-8 database are both using … the UTF-8 encoding. For libc collations: typically collation names, by convention, are truly two-part names of the following structure: {locale_name}.{encoding_name} A "locale" (i.e. "culture") is …
