[rt-devel] Vast numbers of identical queries

RT 3.0.9, Perl 5.0 version 8 subversion 2, Postgresql 7.2.1.

As with when I upgraded to 3.0.8, I'm getting a huge slow-down,
particularly when viewing a ticket with lots of history. Seems to be
slow on every page though.

The CPU is maxed out, and the query goes as:

SELECT * FROM Principals WHERE PrincipalType ILIKE  'User' AND
ObjectId =  '12';

That user is root, because I was viewing the ticket as
root. When I viewed it as myself, it became 24 which is me.

It's cached but if you do it a gazillion times, it's still a huge
hit.

Last time, when I switched to a MySQL server to test the scope of the
problem and back again to Postgres, the problem went away. This time
I'm holding tight in case we can get a proper solution!
