Ouch! But removing pg_size_pretty(numeric) causes another usability
issue, e.g., pg_size_pretty(pg_xlog_location_diff(...)) fails. So how about
removing pg_size_pretty(bigint) to resolve those two issues?
I guess pg_size_pretty(numeric) is a bit slower than bigint version, but
I don't think that such a bit slowdown of pg_size_pretty() becomes
a matter practically. No?
