#
# Using --build-arg PGVERSION=11 we can build pg_auto_failover for any
# target version of Postgres. In the Makefile, we use that to our advantage
# and tag test images such as pg_auto_failover_test:pg14.
#
ARG PGVERSION=14

#
# Define a base image with all our build dependencies.
#
# This base image contains all our target Postgres versions.
