Tom Lane 06af3f9656 Further cleanup of gistsplit.c. ... After further reflection I was unconvinced that the existing coding is guaranteed to return valid union datums in every code path for multi-column indexes. Fix that by forcing a gistunionsubkey() call at the end of the recursion. Having done that, we can remove some clearly-redundant calls elsewhere. This should be a little faster for multi-column indexes (since the previous coding would uselessly do such a call for each column while unwinding the recursion), as well as much harder to break. Also, simplify the handling of cases where one side or the other of a primary split contains only don't-care tuples. The previous coding used a very ugly hack in removeDontCares() that essentially forced one random tuple to be treated as non-don't-care, providing a random initial choice of seed datum for the secondary split. It seems unlikely that that method will give better-than-random splits. Instead, treat such a split as degenerate and just let the next column determine the split, the same way that we handle fully degenerate cases where the two sides produce identical union datums.		13 years ago
