Tom Lane 29c4ad9829 Support "x IS NOT NULL" clauses as indexscan conditions. This turns out ... to be just a minor extension of the previous patch that made "x IS NULL" indexable, because we can treat the IS NOT NULL condition as if it were "x < NULL" or "x > NULL" (depending on the index's NULLS FIRST/LAST option), just like IS NULL is treated like "x = NULL". Aside from any possible usefulness in its own right, this is an important improvement for index-optimized MAX/MIN aggregates: it is now reliably possible to get a column's min or max value cheaply, even when there are a lot of nulls cluttering the interesting end of the index.		2010-01-01 21:53:49 +00:00
