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?
