Обсуждение: pgadmin4 3.5's dependency on psutil is a bit painful

It looks like the most recent release of pgadmin4, 3.5, added a dependency on
psutil==5.4.7 .  This dependency is a bit painful, especially for me,
for a few reasons.

First, it needs a C compiler to build. Second, upstream is not
providing a Linux binary wheel, manylinux or not, to help us out here.
Third, Debian stable ships with psutil 5.0.1 but you have a hard
requirement on 5.4.7. Finally, I tried building my own wheel on what I
thought was a similar system but my pgadmin4/apache is segfaulting
(although this may not be the fault of pgadmin4, I am unable to rule
this out).

So I'd appreciate some feedback here, if you happen to know what the
best way to troubleshoot this segfault in pgadmin4 that would be
great. But for sure I would also ask you to consider relaxing the
dependency on psutil given that virtually all users of your package
now have to maintain a compiler and wheel compilation toolchain
somewhere if they want to run pgadmin4 on Linux.

Thanks Murtuza.

Do you think the requirement for psutil could at least be relaxed to
5.0.1, the version that ships with Debian Stable?

For my segfault - turns out it's due to the psycopg2/libpq/libssl
issue in psycopg2 ticket #543. So, nothing related to pgadmin4.
