Commit 811af9786b introduced palloc() calls into systable_beginscan() and systable_beginscan_ordered(). But there was no pfree(), as is the usual style. It turns out that an ANALYZE of a partitioned table can invoke many thousand system table index scans, and this memory is not cleaned up until the end of the command, so this can temporarily leak quite a bit of memory. Maybe there are improvements to be made at a higher level about this, but for now, insert a couple of corresponding pfree() calls to fix this particular issue.
