Apply fix by oystein.grovlen@sun.com 2010-03-12:
Bug#48213 Materialized subselect crashes if using GEOMETRY type
The problem occurred because during semi-join a materialized table
was created which contained a GEOMETRY column, which is a specialized
BLOB column. This caused an segmentation fault because such tables will
have extra columns, and the semi-join code was not prepared for that.
The solution is to disable materialization when Blob/Geometry columns would
need to be materialized. Blob columns cannot be used for index look-up
anyway, so it does not makes sense to use materialization.
This fix implies that it is detected earlier that subquery materialization
can not be used. The result of that is that in->exist optimization may
be performed for such queries. Hence, extended query plans for such
queries had to be updated.
