you can just do a manual copy

that will require the same amount of space as the original database.
If you're goal is to make a backup, pg_dump is the way to go. Make
note, though, pg_dump will only dump one database

Then use one of the quic

is not asking if x is between 1 and 20 but, rather, if x is a member

That way you can feed it values when testing to validate the calculations
but leave it up to the datetime module to fill in the used value in
