I use EXPLAIN to make sure that my virtual tables' xFilter methods get
called with the proper parameters.
I guess I'm a geek ;)
Geek. :-) I guess I am one too.

Is there any place that explain each of this entries?

However, don't feel you should understand them. They're for geeks only.
The output from EXPLAIN QUERY PLAN can be very useful for people trying to
optimize their code. The output from EXPLAIN is really just for
developers and geeks trying to understand SQLite itself. If you need the
output of EXPLAIN to explain why your code doesn't work, you have serious
problems.
So yes, use EXPLAIN QUERY PLAN if you think it helps. But use EXPLAIN
only if you have spare time.
Simon.
