Build Identifier:

MonetDB has a global variable called "history":

$ mclient
...
sql>select history;
+-------+
| L2 |
+=======+
| false |
+-------+
1 tuple (11.354ms)
sql>set history = true;
operation successful (11.904ms)
sql>select history;
+-------+
| L2 |
+=======+
| true |
+-------+
1 tuple (11.616ms)

But it seems to be unused. Probably it's a left over of the earlier query log implementation. If that's indeed the case, it should be removed.

Reproducible: Always
