Have you created tables in the default template database (template1)?
If so, then those tables will be copied to newly-created databases.
See "Template Databases" in the "Managing Databases" chapter of the
documentation:

This sounds odd -- are you sure you've analyzed the situation
correctly?  Can you provide an exact sequence of steps that
demonstrates this behavior?

I'd guess that you've been working in the template1 database, so
when you create a new database it gets a copy of the tables in
template1.  In general you should leave template1 alone and create
other databases for doing work.

Do you see this problem if you use template0 as the database template?
See the createdb or CREATE DATABASE documentation for instructions
on how to do that.
