i have a Postgis table with about 2 million polyline records.  The most
number of points I have in the geometry field is about 500.  I have a
java program that does a select for most of these records
and do some processing with them before writing them to a file.
Unfortunately, I seem to keep getting this error:

 execute failed: out of memory for query result


This query works fine with less select statement,
my next largest table.  I believe the program is failing at the first
execute after prepare on this table.
