It would be helpful to see the actual SQL statements you're running
instead of a simplified example such as the above, which forces the
reader to make assumptions that might not be true. But in this case
I think we get the idea.

You've referenced the table probe_set (presumably what the example
refers to as table2) but you didn't put it in the FROM clause, so
PostgreSQL added it for you. Some people prefer this to raise an
error instead of a warning, so they turn off the add_missing_from
configuration parameter.
