psql:/home/git/gitlab/db/structure.sql:9: ERROR: permission denied to create extension "btree_gist"

Question

I installed docker-gitlab from here

Step 1. Launch a postgresql container

docker run --name gitlab-postgresql -d \
    --env 'DB_NAME=gitlabhq_production' \
    --env 'DB_USER=gitlab' --env 'DB_PASS=password' \
    --env 'DB_EXTENSION=pg_trgm' \
    --volume /srv/docker/gitlab/postgresql:/var/lib/postgresql \
    sameersbn/postgresql:12-20200524

Step 2. Launch a redis container

docker run --name gitlab-redis -d \
    --volume /srv/docker/gitlab/redis:/data \
    redis:6.2

Step 3. Launch the gitlab container

docker run --name gitlab -d \
    --link gitlab-postgresql:postgresql --link gitlab-redis:redisio \
    --publish 10022:22 --publish 10080:80 \
    --env 'GITLAB_PORT=10080' --env 'GITLAB_SSH_PORT=10022' \
    --env 'GITLAB_SECRETS_DB_KEY_BASE=long-and-random-alpha-numeric-string' \
    --env 'GITLAB_SECRETS_SECRET_KEY_BASE=long-and-random-alpha-numeric-string' \
    --env 'GITLAB_SECRETS_OTP_KEY_BASE=long-and-random-alpha-numeric-string' \
    --volume /srv/docker/gitlab/gitlab:/home/git/data \
    sameersbn/gitlab:14.8.0

But i got these errors from gitlab container:
