POSTGRES_DB=
EOF

# define container name and ports
PGSRV=
PGSRVPORT=

docker run -d --name "${PGSRV}" --env-file POSTGRESENV -p "${PGSRVPORT}":5432 postgres:"$VERSION"

# specify container name for psql configuration, if needed
PGCLI=
docker run -d --name "${PGCLI}" postgres:"$VERSION"

# connect using client container, enter password when prompted
PGUSER=
PGDB=
PGHOST=
PGPORT=
docker exec -it ${PGCLI} psql -h ${PGHOST} -p ${PGPORT} -U ${PGUSER} -W -d ${PGDB}
