The Makefile failed to set HEADERS_pg_plan_advice, so the header wasn't installed. Fixing that reveals another problem: since this is just a loadable module, not an extension, the header file is installed into $(includedir_server)/contrib rather than $(includedir_server)/extension. While we have no existing cases of installing header files there, it appears to be the intent of pgxs.mk. However, this is inconsistent with meson.build, which was using dir_include_extension. Changing that to dir_include_server / 'contrib' makes the install locations consistent across the two builds.
