Marc G. Fournier 69c7f25bed Fixes: ... I found another bug in btree index. Looking at the code it seems that NULL keys are never used to build or scan a btree index (see the explain commands in the example). However this is not the case when a null key is retrieved in an outer loop of a join select and used in an index scan of an inner loop. This bug causes at least three kinds of problems: 1) the backend crashes when it tries to compare a text string with a null. 2) it is not possible to find tuples with null keys in a join. 3) null is considered equal to 0 when the datum is passed by value, see the last query.
