Announcing Release 17 of the PostgreSQL Buildfarm client

I have pushed Release 17 of the PostgreSQL Buildfarm client.

Release 17 has two main features:

  • Modernize the way we do cross-version upgrade tests. Most of the logic for modifying instances to make them suitable for cross version upgrade testing has now been migrated to the Postgres core code in src/test/perl/PostgreSQL/Test/ The new code simply imports this module and leverages its knowledge.
  • Support of building with meson. This is only supported on version 16 or later of Postgres; older branches will continue to use the older toolsets. To enable building with meson there are several new settings, illustrated in the sample configuration file:
    • using_meson this must be set to a true value
    • meson_jobs this controls the degree of parallelism that meson will use
    • meson_test_timeout this is used to multiply the meson test timeout. The default is 3, 0 turns off timeout
    • meson_config This is an array of settings for passing to meson setup. Note that all options need to be explicitly given here - the client disables all auto options. This includes use of zlib and readline, which do not default to on, unlike autoconf setups.

There are also a number of relatively small bug fixes and tweaks (e.g. some improvements in processing typedefs).

The release is available at or
