Thank you for the very detailed review.
Please look at the improved version of the patch (and the `make
installcheck` log with it).

Now I've tried to describe in regress.sgml the behavior, which I want to
I'm not sure that we should name all the assets, that we expect to be
installed, because it can change.

Thanks for the notice. I fixed it.

Thanks again, I've moved the change into ecpg/test.

I've modified the patch to use the installed version of pg_regress. It
simplifies a lot. The main idea of the change is to not build pg_regress.

Regarding test/isolation, we need to change the behavior to build
pg_isolation_regress and isolationtester only. We don't need to build
all the libraries needed as they are already installed in $(DESTDIR)/lib/.
By the way, I wonder why "pg_isolation_regress" and "isolationtester"
binaries are not installed as "pg_regress" is.
As to plpgsql and other PLs, yes, it was my omission. We don't need to
build pg_regress when we use $(pg_regress_installcheck) for any of these,
In contrib/ I've found only one usage of pg_regress_installcheck
(contrib/test_decoding). Fixed it too. We don't need to build the
test-decoding lib as it's installed too.
Also there is an issue with src/test/regress/. We install refint.so and
autoinc.so into $(DESTDIR)/lib/, but don't install regress.so. It makes
impossible to pass "--dlpath='$(DESTDIR)$(libdir)/'" to pg_regress. So
for now I leave dlpath unchanged and it requires building of all the .so's.

The main purpose of the change is to make it possible to perform `make
installcheck` for the installation produced by the binary packages
(pgdg, for example).
The scenario is simple. If I've installed binary packages, how can I
check that the installation is working as expected? (Assuming that I
have corresponding source tarball.)
Currently, I can remove bin/ecpg, lib/libgport, lib/pgxs/, include/ from
the installation directory and `make installcheck-world` will succeed.
But it will not, if I remove bin/psql or lib/adminpack.so.
So the current behavior is at least inconsistent but moreover it's
unsuitable for the user-centric testing of installation. I do understand
that the developer-centric approach was working for years, but may be it
can (or should) be changed someday?
