# postgresql\_schema\_policy
The ``postgresql_schema_policy`` resource applies the necessary SQL DCL
(`GRANT`s and `REVOKE`s) necessary to ensure access compliance to a particular
SCHEMA within a PostgreSQL database.
## Usage
```
resource "postgresql_role" "my_app" {
name = "my_app"
}
resource "postgresql_schema" "my_schema" {
name = "my_schema"
}
resource "postgresql_schema_policy" "my_schema" {
create = true
usage = true
schema = "${postgresql_schema.my_schema.name}"
role = "${postgresql_role.my_app.name}"
}
```
## Argument Reference
* `create` - (Optional) Should the specified ROLE have CREATE privileges to the specified SCHEMA.
* `create_with_grant` - (Optional) Should the specified ROLE have CREATE privileges to the specified SCHEMA and the ability to GRANT the CREATE privilege to other ROLEs.
* `usage` - (Optional) Should the specified ROLE have USAGE privileges to the specified SCHEMA.
* `usage_with_grant` - (Optional) Should the specified ROLE have USAGE privileges to the specified SCHEMA and the ability to GRANT the USAGE privilege to other ROLEs.
* `role` - (Required) The ROLE who is receiving the policy.
* `schema` - (Required) The SCHEMA that is the target of the policy.
## Import Example
`postgresql_schema_policy` supports importing resources. Supposing the
following Terraform:
```
resource "postgresql_schema" "public" {
name = "public"
}
resource "postgresql_schema_policy" "public" {
create = true
usage = true
schema = "${postgresql_schema.public.name}"
role = "${postgresql_role.my_app.name}"
}
```
It is possible to import a `postgresql_schema_policy` resource with the
following command:
```
$ terraform import postgresql_schema_policy.public public
```
Where `public` is the name of the schema in the PostgreSQL database and
`postgresql_schema_policy.public` is the name of the resource whose state will
be populated as a result of the command.
