Thank you, but I had read that article before.
While interesting and useful, it doesn't provide any code example on how 
to actually use dbic::querylog in a cat app (I read the 
$schema->debugobj($ql_instance) and $schema->debug(1) instruction, but 
where do I exactly put them in a cat app, since the cat model's 
connection is delayed until needed ?).

I went on with my tests, and I think your suggestion was right.
If I put this line in the TT template:

[% querylog %]

I get something like DBIx::Class::QueryLog=HASH(0x93b48a8)
where the hash address changes every time I refersh the page.
I think the address should be the same, otherwise I always get a fresh 
object which of course doesn't have any statistics in it... Right ?
