As long as there are no nulls allowed in column 'dst' the
select src,dst,count(dst) from ...
should retrieve the same result.
Try it. It should run faster anyway.
Maybe there are other ways to word your query, but without
more knowledge about your table structure and intentions
I can't tell you what.
Alternatively, you may want to report your error to the
[HACKERS] mailing list - there you might even find more
detailed support.
