Subject: Creating constraint sometime fail in a transaction
Content-Type: text/plain; charset=us-ascii; format=flowed

Hi,

I've a strange bug on PgSQL 7.3.3 with function, constraints and 
transactions.

As the foreign key are too heavy for a massive insert, even set defered, 
we've decided to put them in a function in order to enable/disable them.

So, in such a transaction, first we disable the constraints, using a 
function, then inserting all the data, and afterall put the constraints 
back with another function.

This work fine and quickly... if we do it once. But, when we tried to 
make a big batch with a lot of such transaction, sometime, some 
constraint aren't put back or drop, and the rest of the transactions falls.

So, we're wondering if the action for putting/removing constraint could 
be executed out of the transaction, so that it may overlaps and crash in 
such case.

Does anyone notice the same problem?
