Two remarks:

• As I don't know your application, take this with a grain of salt, but: If I hear a thing like: "creating a table for the day eg 20030219 and" an alarm bell starts to ring in my head and it tries to say: Rethink your design! This doesn't sound right.
  
• As far as a quick glance (off site) got me, you will have to check the dbi-error before dying, as IF NOT EXISTS or the like is not mentioned.
  Code similar to
  

  
  $sth->execute();      # $sth is the statement-handle
  if ($dbh->errstr && $dbh->errstr =~ /Relation\s[a-zA-Z_-']+\salready\s
  +exists/) { # $dbh is the db-handle
      die ...
  }
  [download]

  should get you started. but I strongly suggest to rethink your design! instead.

regards,
tomte
