Filter: (id = 616)"
"-> Subquery Scan on "*SELECT* 2" (cost=0.00..0.27 rows=1
width=0)"

Hi all,
I found this presentation from B. Momjian:
http://momjian.us/main/writings/pgsql/performance.pdf
I'm interested in what he said about " Intersect/Union X AND/OR " , Can I
find a transcription or a video of this presentation? Can anyone explain it
to me?
Thanks,
Thiago Godoi
