Set volume size for postgresql service in docker compose

I have the following fragment of my yaml file.

version: '3'

services:
  db:
    image: dockerized_db
    build: ./DB
    volumes:
      - pgdata:/var/lib/postgresql/data
    ports:
    - 5432:5432

volumes:
  pgdata:

How can I define size of my volume in docker-compose file for that volume used by db container?

The question is about docker-compose, so you are able to set Docker volumes size quota within docker-compose driver opts as the following way:

volumes: 
  tmpfs: 
    driver: local
    driver_opts:
      o: "size=100m,uid=1000"
      device: tmpfs
      type: tmpfs

For details, please go to see https://docs.docker.com/engine/reference/commandline/volume_create/#driver-specific-options

You can create a volume with a size limit and attach it to the container, a good example you can find here

The following example creates a tmpfs volume called foo with a size of 100 megabytes and uid of 1000.

docker volume create --driver local \
--opt type=tmpfs \
--opt device=tmpfs \
--opt o=size=100m,uid=1000 \
foo
