I seriously doubt that the author has 20 years of Oracle DBA experience yet not know why Oracle takes up more disk space that Postgres.
There are so many features in Oracle for which there is no equivalent in Postgres.
-Sharding
-Java Pool
-Oracle Apex
-DB containers and pluggable databases
Many more that I am too lazy to list .
All of these come pre packaged with Oracle.
If you are in an Organization that has 1000s of Oracle db’s per org, you quickly understand that license cost are a minute number but dba and developers are much more expensive .
