Installation (with docker-compose)

version: '3'
services:
  postgres:
    container_name: postgres-15.1-czech
    image: char0n/postgresql-czech-fulltext:15.1
    ports:
     - "5432:5432"
    environment:
      - POSTGRES_PASSWORD=my_secret_password
      - POSTGRES_DB=example_database

Save this yaml as docker-compose.yml and run it with

 $ docker-compose up

Note that Czech fulltext support will be now available in example_database. This is handled by the docker image itself. When you manually create another database, then the Czech fulltext support will not be available automatically. You have to run the following SQL commands inside your new database to enable it:

  create text search dictionary czech_spell
    (template=ispell, dictfile=czech, afffile=czech, stopwords=czech);
  create text search configuration czech (copy=english);
  alter text search configuration czech
    alter mapping for word, asciiword with czech_spell, simple;

Verify installation

Connect to you postgresql database

 $ docker exec -it postgres-15.1-czech psql -U postgres -d example_database

 example_database=# \dF

You should see the following output

               List of text search configurations
