From the normalized one, to the one actually contained within glibc. Recent
versions of glibc also contain symlinks linking the normalized codeset to the
locales with the .UTF-8 ending, but older ones do not.
Maybe handling codeset normalisation for queries would be good, but the locale
values ending in .UTF-8 are more compatible and allow the code to be
simplified. For querying, maybe there should be a locales table which handles
different representations.
This allows easily processing an individual job by id. This may be useful to
use manually, but also when processing jobs in parallel, as forking doesn't
work well with the libpq library used by squee.
