Overview
I had installed the PERFSTAT user (for StatsPack). I was unable to drop the user because it was classified as an administrative user.

Issue
I tried to drop the PERFSTAT user as follows:
drop user perfstat;
The output was:
drop user perfstat * ERROR at line 1: ORA-28014: cannot drop administrative users
Solution
Following the advice in ORA-28014: Cannot Drop Administrative Users (Doc ID 1566042.1), I ran the following command:
alter session set "_oracle_script"=true;
I reran the following SQL command:
drop user perfstat cascade;
This worked.
User dropped.
