Re: Create table command fails with permission denied

Hi,
I'm new to PostgreSQL, and currently facing an issue with PostgreSQL 7.4 database. I'm getting the following error when tried to create a table. Please let me know the steps (with queries) that I should take care to resolve this issue.

cms=# create table test(id character varying(80));
ERROR: could not create relation "test": Permission denied

Thanks in advance,
Venkat

Looks to me as though you are not the owner of the schema nor superuser
nor in a role with permission to create tables in said schema. See the
DBA if it's not you. If it is sign on as postgres (superuser) and grant
yourself some access rights.

Hi Rob,
I'm using postgres account (which is a superuser in the database) to create table. Table creation is working fine in other databases except in this. As postgres user, I granted CREATE, USAGE & ALL privileges to postgres account, still it didn't work.
Please find the snapshots below where it works fine and also where it doesn't work fine. And let me know what rights postgres account is missing to create tables in "cms" database.

==========================================
camd=# \c camd postgres
You are now connected to database "camd" as user "postgres".
camd=# create table test(id character varying(80));
CREATE TABLE
camd=# \c cms postgres
You are now connected to database "cms" as user "postgres".
cms=# create table test(id character varying(80));
ERROR: could not create relation "test": Permission denied
cms=#
==========================================

Thanks,
Venkat

Moderately curious.

I wonder if 'cms' is on a different tablespace? Are there tables in that db?

Btw, I don't have 7.4 so I'm only guessing based on 8.3

Actually, what that is complaining about is that the operating system
refused its attempt to create a filesystem file to hold the table.
It's got nothing to do with permissions inside the database --- there
is something wrong with the filesystem permissions of the data
directory. Or maybe you started the postmaster as the wrong user
(not the one that owns the data directory).

Hi Tom,
Thanks a lot. What you suspected is correct. Permissions are modified on the underlying OS directory of this database. Once the permissions are rectified, I'm able to create tables without any issues.

Thanks to all for your support.
