Обсуждение: Question to schema public

Dear list,

If I create on my system (Postgresql 8.2.4) a new database it gets automatically the schema public.

I would like to know what this schema is for?

On my system I have a couple of different users.
The owner of the public-schema is postgres.

Could it be Fatal to give all of my users the maximum permissions to change that public schema? What could be the
result?

Thank you very much, Kai

By default everyone gets access to objects in schema "public", so that's
select, update, insert, delete on any tables etc. It makes it easy to
get started.

Well, it depends on whether you want your users to be able to create and
drop tables,view,functions etc.

It is kind of a "default schema". If you keep the standard
configuration, then every user can access objects in this schema
without specifying a schema name.

If you don't need schema public, you can also delete it without
breaking anything.

That shouldn't be a problem. It means that
a) every user can create objects in this schema
b) every user can access objects in this schema
   (IF the object allows it)
