Hi Naoya,
I am not able to reproduce the problem. Do you mean pg windows service
installed by installer is not working or bin\pg_ctl binary is not accepting
spaces in the patch ?. Following worked for me i.e.
C:\Users\asif\Desktop\Program files\9.3bin\pg_ctl -D

No adding OFFSET there too didn't give the expected result. The lateral was
handled in subquery and passed as param to the underlying table scan.
I am particularly interested in tables (unlike functions or subqueries)
since, the table scans are shipped to the datanodes and I wanted to test
the
Hi, Asif.
Thank you for response.

I assume foo() takes two argument of type A.
It is related to windows unquoted service path vulnerability in the the
