What pgAdmin version(s) needed these tables/functions?

Hi,

In a database that has been around for a long, long time, there are
several pgAdmin-related relations and functions:

I assume these are things that were needed for some ancient version
of pgAdmin in some ancient version of PostgreSQL? I tried finding
something in current pgAdmin docs about them, but in the pgAdmin 4
or 3 docs I find nothing. Older docs are harder to find.

Can I safely conclude these are obsolete, and get rid of them without
impairing any reasonably recent version of pgAdmin?

With what version did they become obsolete, if they are?

Thanks,
Chapman Flack
