No, that won't make any difference. It runs those utilities with the
--version flag to check what version they are so it knows how to call
them and what servers they will be compatible with. No attempt is made
to connect to any databases or anything.

I suppose it could slow down if you've replaced any of those utilities
with scripts of the same name that do something else - i.e. a pg_dump
script that calls the real pg_dump with the right parameters to
execute a backup. That doesn't seem like something anyone would do
though (and certainly wouldn't be advisable).

Probably the best bet would be to enable debug logging and then check
the timestamps to see what appears to be taking time.
