Hi Andreas,

I hope you did not understand my question. I am not asking query for current database size. I am asking for database growth, i mean predicting the increase in database size over a period like a month just like its available in oracle. For oracle you can see the below link.

http://www.dba-oracle.com/t_database_growth_reports.htm

A huge list of monitoring solutions for Unix/Linux/PostgreSQL. The hot new trend is Prometheus, also you could checkout nagios, icinga, munin, zabbix lots and lots of options there.
You might also try a commercial offering (like e.g. Several Nines), they have some pretty graphs, alarms, alerts of all kinds.
And last but not least, you could have your own monitoring table where you keep periodic snapshots of the live metrics.
You may read here for an overview : https://severalnines.com/blog/key-things-monitor-postgresql-analyzing-your-workload

 Thanks in advance.

Regards,

Why not running a cron job which stores periodically the result of
pg_database_size with a timestamp (simply now())?  Then you have as much
data as you want for growth comparison.

No official thing that can do the job.
You need to DIY, start collecting data (database size, connections 
count, index sizes or so) every day, hour, min or so and then make 
software to analyze it after a while.
