Mind of its own?

Hopefully not, but I feel so helpless.

What happened?

I am using Postgresql 9.6, and the latest phppgadmin. OS is Debian 9.6.

1. Created a database.
2. Created tables inside that database.
3. Dropped that database.


Now, what happens is when I create another database with the same name or different name, all those tables are already
insidethat database!!! I have not run the table create script.  
This is a cruel joke.

What is happening?
