It seems awfully slow, if you're using -k. That switch should remove any
dependency on the data size, but what remains is the number of SQL objects
(databases, tables, functions, etc). If you've got tens or hundreds of
thousands of those, maybe this would be a reasonable time.
As Alvaro said, it's possible that you're hitting some fixable bottleneck;
but to identify what that is we'd need some profiling information.
