I'm trying to create a data table in Postgress in Heroku.
While creating a table I'm getting ERROR: cannot execute CREATE TABLE in a read-only transaction error.
Select commands are working fine, but creating table not working.
What permission I'm missing?
I'm trying to do this using Dataclips and https://app.popsql.com/

Hello salesforce developper,
You seem to have a problem with the credentials of your user. If you read the documentation you will see that the default user credential allow only
Run SELECT on tables in the database
INSERT new data
UPDATE data
DELETE data from tables
On Postgres 10 and above, view some usage statistics and monitoring data
So you need to go to the Credentials tab, find the credential you want to configure, and select one of the permission levels. The levels are:
No permissions — no access privileges on any table in the database
Read-only permissions — read access on every table in the database
Read-write permissions — read and write access on every table in the database, including the ability to delete data, plus the ability to generate values from sequences
Configuring permissions on an existing credential```
