I just ran into a vaguely-related failure: on RHEL8, building
with --with-libcurl leads to failures during check-world:

../../../../src/interfaces/libpq/libpq.so: undefined reference to `dlopen'
../../../../src/interfaces/libpq/libpq.so: undefined reference to `dlclose'
../../../../src/interfaces/libpq/libpq.so: undefined reference to `dlerror'
../../../../src/interfaces/libpq/libpq.so: undefined reference to `dlsym'
collect2: error: ld returned 1 exit status

Per "man dlopen", you have to link with libdl to use these functions
on this platform.  (Curiously, although RHEL9 still says that in the
documentation, it doesn't seem to actually need -ldl.)  I was able
to resolve this by adding -ldl in libpq's Makefile:

-SHLIB_LINK += $(filter -lcrypt -ldes -lcom_err -lcrypto -lk5crypto -lkrb5 -lgssapi_krb5 -lgss -lgssapi -lssl -lsocket -lnsl -lresolv -lintl -lm, $(LIBS)) $(LDAP_LIBS_FE) $(PTHREAD_LIBS)
+SHLIB_LINK += $(filter -lcrypt -ldes -lcom_err -lcrypto -lk5crypto -lkrb5 -lgssapi_krb5 -lgss -lgssapi -lssl -lsocket -lnsl -lresolv -lintl -ldl -lm, $(LIBS)) $(LDAP_LIBS_FE) $(PTHREAD_LIBS)

It doesn't look like the Meson support needs such explicit tracking of
required libraries, but perhaps I'm missing something?  I'm not able
to test that directly for lack of a usable ninja version on this
platform.

Apologies for not noticing this sooner.  I don't think I'd tried
--with-libcurl since the changes to split out libpq-oauth.
