Oops, it seems that one is a bug in ecpg. I found a way to execute it but
that doesn't change much:

I needed 9 seconds and 903642 microseconds for the insert test.
I needed 26 seconds and 882004 microseconds for the selection&projection test.
I needed 75 seconds and 983778 microseconds for the join test.
I needed 0 seconds and 550797 microseconds for the update test.
