Quoting this doesn't work, since in the default case, "$debug" would expand to one empty argument while $debug would expand into zero arguments. In this case, you can use an array with zero or one elements as outlined above, or you can use an unquoted expansion with an alternate value:

debug=""
[[ $1 == "--trace-commands" ]] && debug="yes"
bash ${debug:+"-x"} script

This is better than an unquoted value because the alternative value can be properly quoted, e.g. wget ${output:+ -o "$output"}.

PostgreSQL by default doesn't consume 2 GB of RAM for an InnoDB cache, so I'm not sure it's a good idea.

Currently, the image runs on Buster, so we're more up to date:

Let's try in the container by the way:

We can ignore build failure, it's a Composer out of memory issue. With 2G on WindRiver, I was okay: php -d memory_limit=2G /opt/composer/composer.phar install.
