Attached is new version of these patches. For easier review, I made the new refactorings compared in a new commit

Barring any new feedback or issues, I will commit these.
Maybe you could look at issues with running `make check` under Valgrind
when server built with CPPFLAGS="-DUSE_VALGRIND -DEXEC_BACKEND":
# +++ regress check in src/test/regress +++
# initializing database system by copying initdb template
# postmaster failed, examine ".../src/test/regress/log/postmaster.log" for the
reason
