I did a basic meson build. Full postgresql package, not libpq-only.

The static-only build just works. On master that is. Same as the regular
build.

So yes, meson will handle the static stuff much better.

Applying the v5 patch to the above meson build, will give me a different
error. This time for both the static-only and the regular build:

src/interfaces/libpq-oauth/meson.build:18:22: ERROR: File
oauth-curl.c does not exist.

This.. clears it up, because that file is indeed missing for me on disk.
I assume that's because this file is tracked as a rename in the v5
patch. I can apply this with git, but not directly in the nix build
system. TIL, I need to use "fetchpatch2" instead of "fetchpatch" for
that. Sure thing.

So, with the patch applied correctly, I get the following:

1. Meson regular build:

libpq-oauth-18.so
libpq.so
libpq.so.5
libpq.so.5.18

The libpq.so file has references to dlopen and libpq-auth-18.so, cool.

2. Meson static-only build:

libpq.a
libpq-oauth-18.a

The libpq.a file has no references to dlopen, but plenty of references
to curl stuff.

I'm not sure what the libpq-oauth-18.a file is for.

3. Back to the lipq-only build with autoconf, from where I started. I
only need to add the following line:

make -C src/interfaces/libpq-oauth install

and get this:

libpq-oauth-18.so
libpq.so
libpq.so.5
libpq.so.5.18

Sweet!

4. Of course the static-only build does not work with autoconf, but
that's expected.

So, sorry for the noise before. Now, that I know how to apply patches
with renames, I will try your next patch as well.

Best,

Wolfgang
