Unfortunately the combination of gcc, precompiled headers, ccache and meson currently is not safe without further options. The dependencies emitted by gcc are insufficient to trigger rebuilds when headers "below" the precompiled headers are changed. Whether that's a ccache, gcc or meson bug is debatable. Luckily gcc's -fpch-deps option fixes the issue. This problem occasionally leads to build failures, e.g. if only c.h, postgres.h or pg_config_manual.h change. That's e.g. the case when creating a new major version branch.
