Having exhausted other search options, I was hoping someone might know of a way to change the pgAdmin geometry viewer default tile server? It tries to bring up the OSM one, but we are behind a firewall and it cannot be accessed. However, we have an internal one that could be used. Is this possible?
The tile servers are hardcoded in web/pgadmin/static/js/sqleditor/geometry_viewer.js.
In an installed pgAdmin, you can find this file in a minified form in
.../web/pgadmin/static/js/generated/sqleditor.js; search for "tile.openstreetmap.org".
If you cannot edit that file, then you might be able to configure your internal DNS to redirect
a|b|c.tile.openstreetmap.org to your own server.
