I was measuring the execution time of some queries using different optimizers that provides MonetDB (minimal, default, no_mitosis, sequential and recycler).

Now I want to measure these times but using user-defined optimizer pipeline

For this I am testing with the following command:

MonetDB Septemberoptpipe='optimizer.inline();optimizer.remap();optimizer.deadcode();optimizer.multiplex();optimizer.garbageCollector();' tesisdb

According to the documentation that would be equivalent to using minimal_pipe, the fact is that when I use the expressed command above and run the query throws me the following error:

Function '@ 7 ?.' not defined

I wonder if someone has happened something like this or have any idea how to create different pipes to those provided by the system
