Hi, i have a question:

I have a database and i want to create a administrator user with total
control and another that only could make queries and could not see nor
modify the functions.

The reason is that in the database that i will distribute are the
functions with a big part of the software logics and i do not want
these to be seen by my customers.

Thanks in advance, Guillermo

That's not very open-source of you. LOL.

Aside from database permission issues, which are not a problem, you would also
have to not give them superuser access to their own database server (something
that a lot of companies will not be happy with). Especially if they want to the
possibility of other databases on the server. You would also have to prevent
them from holding onto the backups, something that most companies would not
tolerate at all.

Up until 8.1 it is possible to see all the functions (plpgsql code) in
pgAdmin, even if you don't have access rights to the schema.
I'm not sure how this is in 8.2 or 8.3?

Re: create a limited user in Postgre

That's because the definitions of the functions are not stored in the
schema.

functions are stored in the pg_catalog schema in the pg_proc table and
views are accessible via the multiple pg_get_viewdef functions in the
same schema.

If you block access to that table and fucntion then pgadmin would not be
able to show the function or view definition.

However, as long as the user has access to a backup, they have access to
all the definitions, no matter what you do.
