Exercise 11: PostgreSQL Pages
Draw diagrams of a PostgreSQL heap page
- when it is initially empty
- after three tuples have been inserted
with lengths of 60, 80, and 70 bytes
- after the 80 byte tuple is deleted (but before vacuuming)
- after a new 50 byte tuple is added
Show the values in the tuple header.
Assume that there is no special space in the page.
