New pg_lsn type doesn't have hash/btree opclasses

Hi,

Craig just mentioned in an internal chat that there's no btree or even
hash opclass for the new pg_lsn type. That restricts what you can do
with it quite severely.
Imo this should be fixed for 9.4 - after all it was possible unto now to
index a table with lsns returned by system functions or have queries
with grouping on them without casting.

Greetings,

Andres Freund
