I agree, that we should eventually investigate and solve the original
problem. My suggestion to try to load pftijah on the server was mainly to
find out, whether the problem would also occur in that case, or only in case
pftijah is loaded in the client --- apparently, this attempt was successful,
and we now know much more about the problem ;-)
Since I don't have time to investigate and solve the original problem right
(1) file a proper bug report about it, and preferably add an acompanying
test to CVS that triggers the bug --- basically the test that currently does
not work for you.
(2) you can use the ".dbinit" feature of Mtest.py to do basically your above
change now in Mtest.py directly, but only for a single (or all) tests that
require it --- i.e., add a second version of your test that does work by
loading pjtijah in the server via a <TST>.dbinit with the following content:
(see MonetDB/src/testing/README for details; in particular
+ for frontend tests, a MIL script to be used
instead of the frontends dbinit script.
