PgAdmin4 installation fails for RHEL 7.7 - Mailing list pgsql-pkg-yum

Hi,

while installing PgAdmin4, I am experiencing something very similar to 
what is described in Bug #5075 
(https://redmine.postgresql.org/issues/5075). I can't seem to add a 
comment in Redmine, so I am writing here.

My issue is aslo specific to the RHEL repository: some required packages 
seem to be missing from the public PostgreSQL repository for RHEL.

If I check the available pgAdmin4 related packages in the PostgreSQL 12 
repo for RHEL 7.7 
(https://download.postgresql.org/pub/repos/yum/12/redhat/rhel-7.7-x86_64/), 
here is what I can see:

/pub/repos/yum/12/redhat/rhel-7.7-x86_64/pgadmin4*

pgadmin4-4.15-1.rhel7.x86_64.rpm
pgadmin4-4.16-1.rhel7.x86_64.rpm
pgadmin4-4.17-1.rhel7.x86_64.rpm
pgadmin4-desktop-common-4.15-1.rhel7.x86_64.rpm
pgadmin4-desktop-common-4.16-1.rhel7.x86_64.rpm
pgadmin4-desktop-common-4.17-1.rhel7.x86_64.rpm
pgadmin4-desktop-gnome-4.15-1.rhel7.noarch.rpm
pgadmin4-desktop-gnome-4.16-1.rhel7.noarch.rpm
pgadmin4-desktop-gnome-4.17-1.rhel7.noarch.rpm
pgadmin4-docs-4.15-1.rhel7.noarch.rpm
pgadmin4-docs-4.16-1.rhel7.noarch.rpm
pgadmin4-docs-4.17-1.rhel7.noarch.rpm
pgadmin4-python3-flask-1.0.2-1.rhel7.noarch.rpm
pgadmin4-python3-flask-compress-1.4.0-1.rhel7.noarch.rpm
pgadmin4-web-4.15-1.rhel7.noarch.rpm
pgadmin4-web-4.16-1.rhel7.noarch.rpm
pgadmin4-web-4.17-1.rhel7.noarch.rpm

However, if I check pgadmin4* dependencies for the package 
pgadmin4-4.15-1.rhel7.x86_64.rpm for example, this is what I get:

pgadmin4-docs
pgadmin4-python-Flask-Mail >= 0.9.1

pgadmin4-python-backports.csv >= 1.0.5

pgadmin4-python-wtforms >= 2.2.1
pgadmin4-python3-flask-compress >= 1.4.0
pgadmin4-pytz >= 2018.9

That list is clearly longer than the list of available packages.

The PostgreSQL repositories for Fedora do not seem to have the same 
issue:

https://download.postgresql.org/pub/repos/yum/12/fedora/fedora-31-x86_64/

Is that a bug or am I missing something trivial?
