Tom Lane cbba55d6d7 Support min/max index optimizations on boolean columns. ... Since bool_and() is equivalent to min(), and bool_or() to max(), we might as well let them be index-optimized in the same way. The practical value of this is debatable at best, but it seems nearly cost-free to enable it. Code-wise, we need only adjust the entries in pg_aggregate. There is a measurable planning speed penalty for a query involving one of these aggregates, but it is only a few percent in simple cases, so that seems acceptable.
