So - I THINK I know - that when a row is deleted from a table - the row is not actually removed from the table - but, merely marked as deleted, thus becoming a dead tuple.
AUTOVACUUM - takes care of the process of removing these dead tuples.
My question. If - an insert occurs to that same table before autovacuum comes along, does that inserted record use a dead tuple? Or - does the insert result in an actual added row?
