# This is a Dockerfile that simply builds the plugin for compatibility
# with a specific Postgres version on CentOS 7.3. It is intended to be
# run once so that we can simply extract a properly-compiled .so for
# that platform.
# For actually running a default Postgres build containing the correct
# image, please just run "Dockerfile."
