The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/10/bug-reporting.html Description:
The initial value returned when current_setting() is passed an unset parameter is '<NULL>'. After a SET and a RESET, the value returned by current_setting() is ''. This causes an invalid cast when the value is cast to an integer, as it is expected to be. Tested on Postgres 10 in Linux.
