Changes since previous post:

gsp2.patch: code to generate sort chains updated to guarantee minimal
number of sort steps

Recut patches:

gsp1.patch - phase 1 code patch (full syntax, limited functionality)
gsp2.patch - phase 2 code patch (adds full functionality using the
new chained aggregate mechanism)
gsp-doc.patch - docs
gsp-contrib.patch - quote "cube" in contrib/cube and contrib/earthdistance,
intended primarily for testing pending a decision on
renaming contrib/cube or unreserving keywords
gsp-u.patch - proposed method to unreserve CUBE and ROLLUP

(the contrib patch is not necessary if the -u patch is used; the
contrib/pg_stat_statements fixes are in the phase1 patch)
