#
#   Purpose of this Makefile is to build and install postgres in a local directory
# so that zenith intergation tests would find pg binaries and support files.
#
# 'make postgres' would do following:
#
#   1) run out-of-source build of postgres in REPO_ROOT/tmp_install/build directory (I'm reusing
#  tmp_install path here since it is already present in .gitignore)
#
#   2) installs postgres to REPO_ROOT/tmp_install/
#
#   This Makefile is integrated with cargo build by the means of build.rs file (special file
# that cargo build would run if it is present) which will call `make postgres` if there is no
# tmp_install/bin/postgres binary.
