Split page algorithm was rewrited for 8.2 for multicolumn indexes and API for
user-defined pickSplit function was extended to has better results with index
creation. But GiST can interact with old functions - and it says about this.
That isn't mean some real problem or error - index will be the same as in 8.1,
not better.

Has anyone come across this error before?
LOG: PickSplit method of 2 columns of index
'asset_position_lines_asset_cubespacetime_idx' doesn't support secondary
split
This is a multi-column GiST index on an integer and a cube (a data type
from the postgres cube extension module).
I traced the error to the gistUserPicksplit
<gistsplit_8c.html#ae6afe3060066017ec18f7d40d3f9de8> function in the
gistsplit.c ... I surmise that this method is called whenever a page
split is necessary.
So, I know when this error occurs, but I don't know why.
Thoughts anyone?
Cheers,
Kevin
