In version 5.3.0 we're introducing the possibility to run parallel queries through server-side (a.k.a. named) cursors. To test this feature regularly in a fairly realistic scenario, we extended the benchmark toolkit to have a mode in which all queries are executed through server-side cursors (currently client-side cursors are used). This must be a separate mode because running queries against native PSQL would otherwise turn completely sequential.
See psycopg/psycopg2#941 for why turning the connection into transaction mode is so ugly.
