The typing is even more e.g. for tables or indexes, though. Of course you 
can use the raw form, but why do we have pg_tables if there is pg_class 
anyway.

That could be fixed by having:
pg_database_size(name)
pg_database_size(oid)

The original idea was probably to name "internal" functions with pg_ and 
more user friendly ones without pg_. That does not mean it's a good idea.

Well, I don't feel this is really bloat. I have been using them since the 
creation of the contrib module and have found them quite useful.
