Here I'm just reviewing a couple items in the Sorting section: https://wiki.postgresql.org/wiki/Todo#Sorting
- Consider whether duplicate keys should be sorted by block/offset https://www.postgresql.org/message-id/flat/23321.1205726381%40sss.pgh.pa.us It's moot since we started requiring tid as a tiebreaker for btree indexes, so I'll just remove this. - Consider being smarter about memory and external files used during sorts https://www.postgresql.org/message-id/1196186626.4246.1078.ca...@ebony.site We've had a large number of improvements in this area since 2007, and it seems the ideas in this thread have mostly been done or superseded already. -- John Naylor EDB: http://www.enterprisedb.com
