There is nothing directly "bad" about it.. but:
It's just "an extra step, that might be overseen and is absolutely
required".
I should have written:
Why isn't statistics copied over or why doesnt pg_migrator run analyze by
itself?
The database (of a reasonable size) is useless until statistics is
available.
I guess it is because pg_dump/restore doesn't do it either.
