Speaking of which: how about "Connection bar" instead of "Database bar" as title?

One might expect, that by chosing a connection named "mydb on myuser(at)myserver:port ~myrole" the role would be set as advertised. But that's not how it
works. (And I am not saying it should.)
I don't have a strong opinion here. My reasoning is this:
- pgAdmin is getting increasingly complex.
- Therefore, if a feature is of limited use while introducing chances for errors and misunderstandings, we should consider not having it at all.
If there is use cases where the feature helps a lot, my reasoning is moot.

To be precise: up to 1.12 the "Database bar" only displays information about the _connection_. This is always true, even after SET ROLE.
So does psql.
In 1.14 information about the _active role_ is added. But this can be false.
Firing "select current_user" each time would be an overkill for the purpose. I wouldn't like that. I would rather drop the feature. Typing "SET ROLE
.." is simple enough. No need to confuse others who does not need it.
If we need to distinguish multiple connections with the same parameters, just number / name the connections. In the case of names, one could name it
after the ROLE in use - or after some other equally important criteria.

From what I see under Windows, i would make it broader by maybe 15 %. That should cover most cases. (Not taking into account additional space for the
