Support Docker Compose Issue

[milimyname]

I like the idea of local first software and thank you for trying to solve it and make easier to build a better product for end users and devs!

I found a bug in a tanstack example

Bug with the current .support/docker-compose.yml

Failed to start child :postgres_producer:
{%Protocol.UndefinedError{protocol: Enumerable, value: {:error, {:error, :error, "42601", :syntax_error, "syntax error", [file: "repl_scanner.l", line: "223", routine: "replication_yyerror", severity: "ERROR"]}}, description: ""}, [{Enumerable, :impl_for!, 1, [file: ~c"lib/enum.ex", line: 1]}, {Enumerable, :reduce, 3, [file: ~c"lib/enum.ex", line: 166]}, {Enum, :each, 2, [file: ~c"lib/enum.ex", line: 4399]}, {Electric.Replication.Postgres.Client, :set_display_settings_for_replication, 1, [file: ~c"lib/electric/replication/postgres/client.ex", line: 259]}, {Electric.Replication.Postgres.LogicalReplicationProducer, :init, 1, [file: ~c"lib/electric/replication/postgres/logical_replication_producer.ex", line: 92]}, {GenStage, :init, 1, [file: ~c"lib/gen_stage.ex", line: 1816]}, {:gen_server, :init_it, 2, [file: ~c"gen_server.erl", line: 851]}, {:gen_server, :init_it, 6, [file: ~c"gen_server.erl", line: 814]}]}

Solution .support/docker-compose.yml:

version: "3.3"
name: "electric_example-${PROJECT_NAME:-default}"

services:
  postgres:
    image: postgres:16-alpine
    environment:
      POSTGRES_DB: electric
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: password
    ports:
      - 54321:5432
    volumes:
      - ./postgres.conf:/etc/postgresql/postgresql.conf:ro
    tmpfs:
      - /var/lib/postgresql/data
      - /tmp
    command:
      - postgres
      - -c
      - config_file=/etc/postgresql/postgresql.conf

  backend:
    image: electricsql/electric:latest
    environment:
      DATABASE_URL: postgresql://postgres:password@postgres:5432/electric
      LOGICAL_PUBLISHER_HOST: backend
      AUTH_MODE: insecure
    ports:
      - 3000:3000
    build:
      context: ../packages/sync-service/
    depends_on:
      - postgres

PS: Sorry if it is duplicate

Hey — I just ran through the README instructions to run the example and it worked as expected.

Perhaps you need to run docker pull electricsql/electric to get the latest image?
