see https://www.postgresql.org/docs/9.5/static/app-psql.html for psql options an commands:
psql -d ... -U ...
\d+ measurement_year_month
...
Partition key: RANGE (date_part('year'::text, logdate),
date_part('month'::text, logdate))
Number of partitions: 0
if you want to know how postgresql is retrieving those informations
try -E option for ECHO_HIDDEN
psql -d ... -U ... -E
\d+ measurement_year_month
