    This script creates/restores_from backup copy of given
    file (pushes/pops backup file into/from stack of backups)

    Revision 3

    Caveat: This script may work incorrectly if there are pre-existing
    files which look like backups i.e. files matching ".+\.#[a-zA-Z]*[0-9]+"

    Examples:

-- Given two tables users and login records show first login time on each day
-- SQL is for Postgres

create table users (
  name varchar(64) primary key
);
create table log (
  user_name varchar(64) references users (name) not null,
  date      timestamp
);
