Okay, let assume the testFilteringRangeGeekInterval failure is
unrelated to Tom's patch -> Issue2550810

As for the failure I have on the test, postgresql's docs say that ILIKE
behaviour depends on the locale. Here the commands that I've used to
create the database, maybe my choice of the "C" locale matters.

Created a new postgresql DB:
        rm -r tmpdb/
        mkdir tmpdb
        initdb -D tmpdb/ -U rounduptest --locale=c --encoding=UTF8
        pg_ctl -D tmpdb/ -l logfile -o '-k ./' start
