Re: Resetting the pgadmin4 web user credentials

Kevin,
I don't think that the pgAdmin user and the database user are necessarily
the same thing (though I could be wrong) [see:
https://www.pgadmin.org/docs/pgadmin4/5.4/user_management.html ]. The
pg_hba.conf file defines what users/machines/methods are allowed to connect
to a postgresql server. So for the first line in your example:

host all all my.dbserver.ip.addr/32 trust

this would mean; *host * == connections made over TCP/IP, the first *all* ==
which databases, the second *all* == which users, the
*my.dbserver.ip.addr/32* == means *only* allow connections originating from
that *exact* ip address, and *trust* == allow connections without a
password or any other form of authentication [see:
https://www.postgresql.org/docs/13/auth-pg-hba-conf.html ]. I am guessing
that you have gotten the pgAdmin users confused with the postgresql
database users.

I would imagine that the pgAdmin server would need an entry in the
pg_hba.conf file for whatever machine pgAdmin is running on and I would be
amazed if it was using *trust* (or *no* authentication) to connect with. I
use pgAdmin exclusively in desktop mode, so hopefully someone else who's
more familiar with server mode will chime in.

I hope that helps,

rik.
