usage_description = "
Runs all of the scripts given as arguments against multiple PostgreSQL versions using docker
Uses postgres.sh to boot a PostgreSQL docker environment and pipe source statements in to the container
Sources each script in PostgreSQL in the order given
Runs against a list of PostgreSQL versions from the first of the following conditions:
- If \$ POSTGRES_VERSIONS environment variable is set, then only tests against those versions in the order given, space or comma separated, with 'x' used as a wildcard ( eg. '10.x , 11.x , 12.x' )
- If \$ GET_DOCKER_TAGS is set and dockerhub_show_tags.py is found in the \$ PATH ( from DevOps Python tools repo) , then uses it to fetch the latest live list of version tags available from the dockerhub API, reordering by newest first
- Falls back to the following pre-set list of versions, reordering by newest first:
$( tr ' ' '\n' <<< " $postgres_versions " | grep -v '^[[:space:]]*$' )
