Something along the lines of

do $$
declare fname text;
begin
for fname in select oid::regprocedure from pg_proc where proname = 'foo' loop
execute 'drop function ' || fname;
end loop;
end$$;

Adjust WHERE condition to taste.

People periodically ask for extensions flavored more or less like this,
but I'm suspicious of building any such thing into the core. There's too
little commonality in the exact conditions they want to search on.
Leaving it at the level of a scripting problem, as above, allows arbitrary
customization of the search condition.
