WARNING: Flag `--gce-zone` is deprecated

In the following tutorial:

Create a PostgreSQL Cloud SQL Instance

When I enter

gcloud sql instances create --gce-zone us-central1-f \
> --database-version POSTGRES_9_6 --memory 4 --cpu 2 memegen-db

I'm getting the following message:

WARNING: Flag `--gce-zone` is deprecated and will be removed by release 255.0.0. Use `--zone` instead.

Recommendation:

change

gcloud sql instances create --gce-zone us-central1-f \
> --database-version POSTGRES_9_6 --memory 4 --cpu 2 memegen-db

to

gcloud sql instances create --zone us-central1-f \
> --database-version POSTGRES_9_6 --memory 4 --cpu 2 memegen-db
