Bug reference: 15950 Logged by: Daniel Adeniji Email address: daniel_adeniji@hotmail.com PostgreSQL version: 11.4 Operating system: Windows 10 Description:
Issued the query pasted below :-
...
Result :- =========
1) pg_freespace.avail is 0
Your query didn't even return pg_freespace.avail. It returned some convoluted thing that might depend on it.
Why is this a bug? Why is 0 wrong? What should it be instead? If pg_freespace.avail is wrong, why not how a query that shows that, rather than something else tangentially related to it? What is the actual output of the query you do show?
