I'm testing all collations with ICU-51.2 with the same data as previously,
and I just see it crashing at the 103th and a few other az-* after that:

2017-08-07 19:09:26.538 CEST [59353] LOG:  server process (PID 60458) was
terminated by signal 11: Segmentation fault
2017-08-07 19:09:26.538 CEST [59353] DETAIL:  Failed process was running:
select count(distinct wordtext collate "az-Latn-AZ-u-co-search-x-icu") from
words_test
2017-08-07 19:09:26.538 CEST [59353] LOG:  terminating any other active
server processes
2017-08-07 19:09:26.538 CEST [60316] WARNING:  terminating connection because
of crash of another server process

I don't have core files for this run but that's probably enough to say
that ICU-51 is no good for us.

Best regards,
