Subject: [GENERAL] Unauthorized users can see db schema and read functionsHi,
I've noticed that any user who can logon to a db cluster can read the schema of all databases in it, including the code of all plpgsql functions. Even in schema's he/she doesn't have access to. For tables it just says 'access denied for schema bla', after which the structure is still shown to the user. For functions, there is no warning at all, you can just read (copy, paste) away.
I use pgAdmin3 1.6.2 as a front-end for both linux and windows servers, but I don't think restricting schema information should be a front-end responsibility.
o Why is schema information not restricted?
This
is a limitation of <= 8.1.x.
In 8.2
the "CONNECT" priviledge was introducted on the database (still wondering why it
was not done earlier).
Probably something similar should be done on the schema's too
;)
o Is there any way to prevent this, other than starting another cluster for this user's database
- Upgrade to 8.2...
- (Not sure and seems to contradict with your statement) you can move everything into a different schema, since public will always be readable, and others can be restricted
People
who know it for sure should correct me, of course.
I
found the behaviour strange too...
