I don't like how timetz was highlighted. From the PostgreSQL docs[1]: "Time zones in the real world have little meaning unless associated with a date as well as a time, since the offset can vary through the year with daylight-saving time boundaries."

Also, I quote: "It's Postgres or Postgres-Que-Ell, not Postgre-Es-Que-Ell". And then a slide shows "PostgresQL" while http://postgresql.org shows "PostgreSQL". That pronounciation makes no sense to me if the slide is correct.
