Azure Database for PostgreSQL not supported?

I am trying to import our existing Azure Data Factory/PostgreSQL set-up into Terraform. In Azure there are two PostgreSQL connectors: ‘PostgreSQL’ and ‘Azure Database for PostgreSQL’ We are using the latter as it supports Mapping Data Flows and the former doesn’t.
The PostgreSQL Linked Service created by Terraform seems to use the first connector and there doesn’t seem to be an option to use the second connector. Is this right or am I missing something?
