Hi,

how come, if you create a user with no permissions at all, having been granted nothing, he can still log into any database, list available tables, create new here, and then delete them again. Seems odd...:

medusa:~% createuser odd
Shall the new user be allowed to create databases? (y/n) n
Shall the new user be allowed to create more new users? (y/n) n
CREATE USER
medusa:~% psql -U odd cnv
Welcome to psql 7.3.7, the PostgreSQL interactive terminal.

Type: \copyright for distribution terms
\h for help with SQL commands
\? for help on internal slash commands
\g or terminate with semicolon to execute query
\q to quit

cnv=> \dt
List of relations
Schema | Name | Type | Owner
--------+---------------+-------+---------
public | theaders | table | jonasfh
public | theadervalues | table | jonasfh
(2 rows)

cnv=> create table oddtable();
CREATE TABLE
cnv=> \dt
List of relations
Schema | Name | Type | Owner
--------+---------------+-------+---------
public | oddtable | table | odd
public | theaders | table | jonasfh
public | theadervalues | table | jonasfh

(3 rows)

cnv=> drop table oddtable;
DROP TABLE

Is this right, or is there something wrong with my settings in some way?

regards Jonas)

*DO* make sure that one user has explict access before revoking all on
public though.
