Thank you for pointing me to the pg_config options. I didn't know and will take a look.

As already mentioned in my original post, there are some cases a "normal" user (in my terminology it is a db responsible not experienced with C programming practice) may use a manual recompile:
The user should be able to recompile the package (which is really very easy with meson after some setup of developer packages) without deeper knowledge of C programming with the original configuration of the distribution.
In production I use the binary distribution from PGDG and additionally compile the latest/beta versions for a compatibility check.
