Hello all:
Attached is a view I wrote for postgres 7.4 that seems to provide pretty
accurate reporting of table sizes. For each non-system table in a database
it shows base table size, size of any related TOAST data, and aggregate size
of indexes.
The code is somewhat ugly in that it contains a bunch of CASE statements the
sole point of which is to transform the occasional NULL into a 0.
Object sizes are computed from pg_class.relpages with an assumed page size
of 8192.
Comments and improvements most welcome.
