Hi,
Our database is growing fast. I want to create a cronjob that should
tell me what is the current size of the database on each day.
How can I find this from the database? Is there any pre-written scripts
written by somebody to share?
Regards
skarthi

Be aware of linebreaks ...
[Galadriel: cug ] cug $ psql -U postgres -c "select pg_size_pretty
(pg_database_size('testdb'));"
pg_size_pretty
----------------
495 MB

Hi,
there is an administrative function called pg_database_size(name), as in
SELECT pg_database_size('mydb'); which returns the disk space used by
the database with the specified name.
See Chapter 9.20.
cheers,
Hubertus
