Thread: expression_tree_walker: Unexpected node type 711

I am having a problem with a select statement and the error 
expression_tree_walker: Unexpected node type 711 is being returned when 
I am trying to execute a rather simple SELECT statement.

Any insight anyone could give me would be greatly appreciated. And if 
this is the wrong place to ask this then if someone could point me in 
the right direction that would be swell.

TALE STRUCTURE:             Table "public.official_hour"        Column         |       Type       | Modifiers
-----------------------+------------------+----------- calendar_date         | date             | not null
official_opening_hour| double precision | office_closed         | boolean          |
 
Indexes: official_hour_pkey primary key btree (calendar_date)

SOME DATA THAT LIVES IN TABLE:
select * from official_hour limit 10; calendar_date | official_opening_hour | office_closed
---------------+-----------------------+--------------- 2018-11-08    |                       | 2018-11-09    |
             | 2018-11-10    |                       | t 2018-11-11    |                       | t 2018-11-12    |
                | 2018-11-13    |                       | 2018-11-14    |                       | 2004-08-11    |
             9 | f 2004-08-12    |                     9 | f 2004-08-13    |                     9 | f
 

SQL THAT IS THROWING ERROR:
select calendar_date
from official_hour
where official_hour is not null and office_closed = False and calendar_date >= date'2004/01/01' and calendar_date <=
date'2004/08/23'
order by calendar_date

RESULTS:
ProgrammingError: ERROR:  expression_tree_walker: Unexpected node type 711

Anyone see something here I don't? Could this be a result of having a 
date object as part of the primary key?

7.4 will give a more helpful error message:

ERROR:  relation reference "official_hour" cannot be used in an expression
