Mainly for general readability. Some notable changes: - Postgres can be built without the rest of the repository, and in particular without any of the Rust bits. Some CI scripts took advantage of that, so let's make that more explicit by separating those parts. Also add an explicit comment about that in the new postgres.mk file. - Add a new PG_INSTALL_CACHED variable. If it's set, `make all` and other top-Makefile targets skip checking if Postgres is up-to-date. This is also to be used in CI scripts that build and cache Postgres as separate steps. (It is currently only used in the macos walproposer-lib rule, but stay tuned for more.) - Introduce a POSTGRES_VERSIONS variable that lists all supported PostgreSQL versions. Refactor a few Makefile rules to use that.

Makefile
# Sub-makefile for compiling PostgreSQL as part of Neon. This is
|
|
# included from the main Makefile, and is not meant to be called
|
|
# directly.
|
|
#
|
|
# CI workflows and Dockerfiles can take advantage of the following
|
|
# properties for caching:
|
|
#
|
|
# - Compiling the targets in this file only builds the PostgreSQL sources
|
|
# under the vendor/ subdirectory, nothing else from the repository.
|
|
# - All outputs go to POSTGRES_INSTALL_DIR (by default 'pg_install',
|
|
# see parent Makefile)
|
|
# - intermediate build artifacts go to BUILD_DIR
|
|
#
|
|
#
|
|
# Variables passed from the parent Makefile that control what gets
|
|
# installed and where:
|
|
# - POSTGRES_VERSIONS
|
|
# - POSTGRES_INSTALL_DIR
|
|
# - BUILD_DIR
|
|
#
|
|
# Variables passed from the parent Makefile that affect the build
|
|
# process and the resulting binaries:
|
|
# - PG_CONFIGURE_OPTS
|
|
# - PG_CFLAGS
|
|
# - PG_LDFLAGS
|
|
# - EXTRA_PATH_OVERRIDES
