[Monetdb-developers] Key constraints and optimizers...

Dear developers....

I was checking the status of the SQL test web-site (cvs branch) and I 
found some red ones.

In the test src/test/BugConstraint/delete_primarykey_1643845.sql

If I run the normal Mtest the test is red (the err output).

The constraint error given is for the foreign key and not for the 
primary key (as in the stable output).
If I ran with M4 the test is green the same happens if I set the 
optimizers off.

So we can conclude that the reason for this test being red are the 
optimizers and nothing else in SQL module.

I tried to give a look to see which optimizer is breaking the test, but 
no results. Tomorrow I will continue.

I also think that all the tests that are red (the ones related with 
primary keys) are due this problem.

Should I open a bug or this is enough? Because it is an existent test 
that is red ;)
