README.dbsize

This module contains two functions that report the size of a given
database or relation. E.g.,

SELECT database_size('template1');
SELECT relation_size('pg_class');

These functions report the actual file system space. Thus, users can
avoid digging through the details of the database directories.

Copy this directory to contrib/dbsize in your PostgreSQL source tree.
Then just run make; make install. Finally, load the functions into any
database using dbsize.sql.

When computing the size of a table, it does not include TOAST or index
disk space.
