Is it is possible to create Policy Tag in Data Catalog for Bigquery Column level security using Terraform . I'm not seeing any resource for policy tag in terraform documentation.
https://www.terraform.io/docs/providers/google/r/data_catalog_entry.html
Managing Policy Tags using Terraform is not yet supported as of today (2020-09-24), but it's being worked on: see https://github.com/hashicorp/terraform-provider-google/issues/6075.
