Get The Size Of A Database

If you have connect access to a PostgreSQL database, you can use the pg_database_size() function to get the size of a database in bytes.

> select pg_database_size('hr_hotels');

Just give it the name of the database and it will tell you how much disk space that database is taking up.

Checkout the Postgres docs for more details.
