+
+This might be a DB permission issue. 
+
+1. Validate db user permission issue 
+
+Try creating a new database. 
+
+```bash
+STATEMENT: CREATE DATABASE "litellm"
+```
+
+If you get:
+
+```
+ERROR: permission denied to create 
+```
+
+This indicates you have a permission issue. 
+
+2. Grant permissions to your DB user
+
+It should look something like this:
+
+```
+psql -U postgres
+```
+
+```
+CREATE DATABASE litellm;
+```
+
+On CloudSQL, this is:
+
+```
+GRANT ALL PRIVILEGES ON DATABASE litellm TO your_username;
+```
