Works for me in 11.0, no doubt as a result of this last-minute fix:
https://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=db9034bf7653fa527e2531e1a713dbbd37066a6b

ERROR: stack depth limit exceeded
HINT: Increase the configuration parameter "max_stack_depth" (currently 2048kB), after ensuring the platform's stack depth limit is adequate.
