The new names are intended to match those in an upcoming patch that adds
a few GUCs to configure the SLRU buffer sizes.
Backwards compatibility concern: this changes the accepted names for
function pg_stat_slru_rest(). Since this function recognizes "any other
string" as a request to reset the entry for "other", this means that
calling it with the old names would silently reset "other" instead of
doing nothing or throwing an error.
