PostgreSQL version: 9.5.4
Operating system: 4.4.0-34-generic #53-Ubuntu
Description:

When I use postgres function:

SELECT generate_series('2016-08-01', '2016-08-31', '1
day'::interval)::date

it gives me the corresponding list of days but for some reason it misses the
day 2016-08-31.
-I've tried this with other months and it works correctly, also if I use it
for the same dates but on 2015 it works fine.
-This started failing after we upgraded our system to the version 9.5.4,
I've tryed it in an older release that we had installed and it worked.

Best regards.
