We only need to invoke constraint exclusion on partitioned tables when they are a partition, and they themselves contain a default partition; it's not necessary otherwise, and it's expensive, so avoid it. Also, we were trying once for each clause separately, but we can do it for all the clauses at once. While at it, centralize setting of RelOptInfo->partition_qual instead of computing it in slightly different ways in different places. Per complaints from Simon Riggs about 4e85642d935e; reviewed by Yuzuko Hosoya, Kyotaro Horiguchi. Author: Amit Langote. I (Álvaro) again mangled the patch somewhat.
