Issue with postgres 11beta2 and powa on debian stretch amd64 - Mailing list pgsql-pkg-debian

Hello,

I installed postgresql-11-powa on a fresh debian stretch amd64 with
postgresql-11 beta2

I got several errors "set-valued function called in context that cannot accept a
set" which should be fixed :
2018-07-22 14:16:22.209 CEST [30135] WARNING:  powa_take_snapshot(): function
"powa_user_functions_snapshot" failed:

            )
            INSERT INTO powa_user_functions_history_current

                ROW(now(), (r).calls,
                    (r).total_time,
                    (r).self_time)::powa_user_functions_history_record AS record
                FROM func"
        PL/pgSQL function powa_user_functions_snapshot() line 10 at SQL statement
        SQL statement "SELECT powa_user_functions_snapshot()"
        PL/pgSQL function powa_take_snapshot() line 76 at EXECUTE
        SQL statement "SELECT powa_take_snapshot()"


FYI, I do not have this error if I build powa from github's sources. So, I seems
it is a packing issue.

Thanks
