When running the following query:
select
cume_dist(1) within group (order by a desc),
rank(1) within group (order by a desc),
dense_rank(1) within group (order by a asc),
percent_rank(1) within group (order by a asc)
from (values(1)) t(a);
My JDBC connection is immediately terminated:
SQL Error [08006]: An I/O error occurred while sending to the backend.
An I/O error occurred while sending to the backend.
Connection reset
The issue depends on a certain set of combinations of the above function calls. Each function can be called individually without problems. Some functions can be combined without problems as well.
The issue can be reproduced in pgAdmin III and pgAdmin 4.
I'm using PostgreSQL 9.6.5 on Windows 10 x86-64
