I don't really follow: Including the operating system in PG_VERSION_STR,
as we're doing in autoconf, seems orthogonal to extra_version? Adding linux
into extra_version would result in linux showing up in e.g.
which doesn't seem right.
I think there's a further deficiency in the PG_VERSION_STR the meson build
generates - we use the build system's CPU. Autoconf shows $host, not $build.
For comparison, on my machine autoconf shows:
PostgreSQL 16devel on x86_64-pc-linux-gnu, compiled by gcc-12 (Debian 12.2.0-9) 12.2.0, 64-bit
whereas with meson we currently end up with
PostgreSQL 16devel on x86_64, compiled by gcc-13.0.0
I still don't think it makes sense to try to copy (or invoke)
config.guess. Particularly when targetting windows, but even just having to
keep updating config.guess in perpituity seems unnecessary.
Given we're looking at improving this, should we also add 32/64-bit piece?
If so, we probably should move building PG_VERSION_STR to later so we can use
SIZEOF_VOID_P - configure.ac does that too.
With extra_version set to -andres the attached results in:
PostgreSQL 16devel-andres on x86_64-linux, compiled by gcc-13.0.0, 64-bit
