Re: That EXPLAIN ANALYZE patch still needs work

Well, that's certainly unsurprising, but the question is why it's such
a large overhead for you when it's not on other apparently-similar kit.

If anyone else is still following this discussion, could you try the
test case Simon gave a bit earlier (select count(*) from 100000-row
table, check \timing with and without explain analyze)?  If we could get
a clearer picture of which platforms show the problem and which don't,
maybe we could make some progress.

(BTW, I just tried it on my Apple Powerbook G4, and got results in line
with what I get elsewhere.  So I've now tried it on three very different
CPU types and OSes, and not duplicated Simon's problem on any of them.)
