Perhaps. Having a default description for the collations imported by
initdb is nice to have, but because of the gap with collations defined
after initialization it seems to me that there is an argument to
switch to that function for psql instead of grepping the default
description added to pg_description. Enforcing a comment for a
collation manually created based on what libicu tells us does not
feel right either, as we don't enforce a comment for the creation of
other objects.
