Postgres PgAdmin server pane contains lot of servers.
BigSQL Postgres 10.1 was installed in Windows 10. It installed also PgAdmin III LTS by BigSQL.
In this PgAdmin server window only servers added in it are shown. For example, if server named testbigsqlsever is added, BigSQL pgAdmin shows it:
How to force it to show also servers installed by earlier PgAdmin III ? Earlier pgAdmin remains also in this computer and it shows all servers.
It looks like both pgadmins store server list in
HKEY_CURRENT_USER\Software\pgAdmin III\Servers
but PgAdmin III LTS by BigSQL does not show servers added by standard pgAdmin.
Since standard pgAdmin does not support Postgres 10 and pgAdmin IV does not have config editors and has poor user interface BigSQL pgAdmin should used. There are number of servers added earlier and manually adding them all requires lot of work
