+## Usage
+
+```hcl
+resource "postgresql_script" "foo" {
+  commands = [
+    "command 1",
+    "command 2"
+  ]
+  tries = 1
+  timeout = 1
+}
+```
+
+## Argument Reference
+
+* `commands` - (Required) An array of commands to execute, one by one.
+* `tries` - (Optional) Number of tries of a command before raising an error.
+* `timeout` - (Optional) Time in second between two failing commands.
+
+## Examples
+
+Revoke default accesses for public schema:
+
+```hcl
+resource "postgresql_script" "foo" {
+  commands = [
+    "BEBIN",
+    "SELECT * FROM table",
+    "COMMIT"
+  ]
+  tries = 3
+  timeout = 1
+}
