Description:
I tried to ask a question on Stackoverflow but it seems to be a bug:
Hopefully is all the details required in the Stackoverflow question, in
short I have a "table_2017_1" which Inherits "table_2017", so no data or
index are stored directly in "table_2017". When I run a question on
table_2017 it uses the index on table_2017_1 but when I run the exact same
question on "table_2017_1" it doesn't evaluate the index and perform a
sequence scan instead.
