"existent" is a word according to my dictionary, so "non-existent"
is fine. "extant" is also a word but it's less common and doesn't
really mean the same thing --- it carries a connotation of "still
in existence, surviving". So you might say "Stonebraker's papers
about Postgres from the '80s are still extant". "Existent" just
means "in existence" without any particular implication about time
passing, so it's probably what is meant in most cases.

(Actually, in the particular context here, I guess "extant" would
be sensible, but it would be rather hi-falutin' usage. I'd go
with "existent".)
