The oldest version of the tree I have around is v11, and if I enable
EXEC_MERGEJOINDEBUG I get the exact same failure. This means that
this has been unnoticed for at least 10 years.
So question time: Is this debugging code still relevant and wouldn't
it be better to just remove it? It looks pretty clear to me that
nobody is using this #define at all, or this failure would have been
noticed a long time ago.
Note that an all-time search of EXEC_MERGEJOINDEBUG on pgsql-hackers
and pgsql-bugs points only at this thread.
