Deploying ERPnext docker using postgresql

Is it possible if i overide mariadb with postgresql where i alread have a instance running in AWS RDS ?
Will ERPnext will create a new schema and table creation happen at installation time ?

Yes, It’s possible.

You can run below command:

bench new-site <your-site.com> --admin-password 'your-password' --db-host rds-dns-address --db-name your-erp-db

Thanks , for the reply by exeucting this command will there be a schema created or can i specifc an exsting schema name as well ?

Can any one help me out on this pls got struck from 3 days

ERPNext doesn’t support Postgresql but Frappe framework does
