Hi folks,

Had some time to rework this patch from the two that had previously been
here into two separate parts:

1) A basic refactor of the existing code to easily handle expanding the
units we use into a table-based format. This also includes changing the
return value of `pg_size_bytes()` from an int64 into a numeric, and
minor test adjustments to reflect this.

2) Expanding the units that both pg_size_bytes() and pg_size_pretty()
recognize up through Yottabytes. This includes documentation and test
updates to reflect the changes made here. How many additional units we
add here is up for discussion (inevitably), but my opinion remains that
there is no harm in supporting all units available.

Best,

David
