I've test the attached patch in all variants from v9.5..15 to supported
versions 10..master. The script test.sh for 9.5->10 and 9.6->10 upgrades
works fine without any patch.
In 9.4 there is a regress test largeobject to be patched to allow
upgrade test from this version.So i've stopped at 9.5.
This is clear that we limit the destination version for upgrade test to
the supported versions only. In our case destination versions
starting from the 10th inclusively.
But is there are a limit for the source version for upgrade test from?
