If I just want to install postgres into a prefix without 'postgresql' added in
a bunch of directories, e.g. because I already have pg-$version to be in the
prefix, there's really no good way to do so - you can't even specify
--sysconfdir or such, because we just override that path.
At least for the libraries, the point of the 'postgresql' subdir IMO
is to keep backend-loadable extensions separate from random libraries.
It's not great that we may fail to do that depending on what the
initial part of the library path is.
Agreed, extensions really should never be in a path searched by the dynamic
linker, even if the prefix contains 'postgres'.
To me that's a separate thing from adding postgresql to datadir, sysconfdir,
includedir, docdir... On a green field I'd say the 'extension library'
directory should just always be extensions/ or such.
I think we should get the two build systems to produce the same
installation layout when given equivalent options.
Unless someone comes up with a proposal to address the above broader
issues, also taking into account current packaging practices etc., then
I think we should do a short-term solution to either port the
subdir-appending to the meson scripts or remove it from the makefiles
(or maybe a bit of both).
