pgadmin3 in Fedora 32 Workstation

[Anil Felipe Duggirala]

hello,

I have 2 separate questions regarding pgadmin installation in Fedora 32.

1. pgadminIII, I believe only supports postgresql up to version 11.x. 
The default version (fedora repo) of postgresql is 12.3. So the pgadmin3 
(pgadmin4 is not available) package in the default repository is not 
compatible with the default postgresql package. Is this correct?

2. A couple of days ago, my terminal prompt changed from 
"username@machinename", to "username@localhost". Did this maybe happen 
after installing postgresql and/or pgadmin? Could anyone point me in the 
direction of the documentation that explains how this all (domains, 
setting them in Fedora, implications, etc.) works?

thank you very much,

Anil
