So looking at this, it seems that for the most part pg_size_bytes()
will parse any output produced by pg_size_pretty(). The exception is
that there are 2 versions of pg_size_pretty(), one that takes bigint
and one that takes numeric, whereas pg_size_bytes() returns bigint, so
it can't handle all inputs. Is there any reason not to make
pg_size_bytes() return numeric? 

It would still be compatible with the example use cases, but it would
be a better inverse of both variants of pg_size_pretty() and would be
more future-proof. It already works internally using numeric, so it's
a trivial change to make now, but impossible to change in the future
without introducing a new function with a different name, which is
messy.

Thoughts?
