D7 recipe with mysql tries to install postgres

[garrettw]

PostgreSQL should not be trying to install as I have nothing in my lando file asking for it.

Lando version: 3.1.4

.lando.yml:

name: myapp
recipe: drupal7
config:
  php: '7.3'
  composer_version: '2.4.4'
  via: apache:2.4
  webroot: .
  xdebug: true
  database: mysql:5.7
  config:
    php: .lando/php/php.ini

services:
  appserver:
    ssl: true
    build_as_root:
      - apt-get update
      - apt-get install -y libcurl4-openssl-dev libxml2-dev
      - printf "\n" | pecl install solr-2.5.1
      - docker-php-ext-enable solr
  pma:
    type: phpmyadmin
    hosts:
      - database

proxy:
  pma:
    - pma.myapp.lndo.site

The problematic part of the build output:

I'm guessing this was part of the apt-get update in the appserver's build_as_root; Lando's appserver containers are built on Debian images, and I believe Debian comes with Postgres by default.

If someone is in a similar position, I'm guessing you could run an apt remove postgresql or similar as an initial step.

Now I see why Alpine and other lean images are a thing ;)
