Calculating database sizes using a script - Mailing list pgsql-novice

Hi all

      I have a client that is running a total of 190 Postgresql databases.

                I am busy with an audit on the database sizes, performance tuning,etc...

                However to check the database sizes is quite tedious as some of the servers are running up to 24 databases on one instance.

                Due to security restrictions I am not yet able to use pgadmin / pgphpadmin and need to manually calculate this using ‘SELECT pg_size_pretty(pg_database_size(''));’

                Is there a way of running this in a script for each database in the instance without having to manually type in each database name?

                For instance. Let the script extract the database names and then check the sizes printing it to an output file / screen?
