PG SQL scripts

Hi,

Does anyone know of any websites (or care to share) that have PG sql
scripts for querying the pg_ views/tables, (there's 000's for Oracle
dba_ v$ views). I'm after storage (sizes etc) info regarding the
applications tables/indexes, also how can I format the output-ted
columns into a more readable format.

Many thanks for any assistance.

Cheers,
Nigel
