You really should add commentary, especially since you never demonstrated
the tst role (I advise picking different names for all of the objects in
the future) being unable to login. Which they should be able to since
public is shown to have "c" connect privileges (=Tc/tst)

This next command is pointless, it is a no-op, as soon as you made them
owner of the tst database they already had all privileges to it, granted by
the same user that created the database. And only it, that command is not
recursing through the database into schemas and tables and adding more
permissions. That isn't how this all works, a database is an object.
While it is also a concept that encompasses the entire schema within it the
permissions system only cares about the first definition.

What are you trying to demonstrate here?
