First, as some other msg states the views will estimate the sizes,
dbsize uses actual file sizes. Second, in contrast to CKL, I would *not*
use these fancy new system views, because they mean yet another
dependency for pgAdmin.

What do you mean? Those views aren't an option for me.

Not more dangerous than "drop table pg_class". The file functions are
restricted to the cluster directory.

Hm, don't remember that, AFAIR it was removed after a discussion between
Tom and Dave that kill -9 would stress a code path that still isn't
elaborated too much. But in the situations mentioned above, I took the
risk and would like a function for that.
