The latest patch still applies (with some fuzz), builds and the regression tests pass.
Attached latest patch, which applies cleanly on latest source.
I see that Robert made a number of changes and posted a v6 along with some numbers which he described as lacklustre, but then fixed a row estimate problem which was discouraging parallel joins (commit 0c2070ce). Rushabh posted a v7 and test results which look good. As far as I can see there are no outstanding issues or unhandled review feedback. I've had a fresh read through of the latest version and have no further comments myself.
I've set this to ready-for-committer now. If I've misunderstood and there are still unresolved issues from that earlier email exchange or someone else wants to post a review or objection, then of course please feel free to set it back.
Thanks Thomas.
BTW There is no regression test supplied. I see that commit 5262f7a4 adding parallel index scans put simple explain output in "select_parallel" to demonstrate the new kind of plan being created; perhaps this patch should do the same? I know it wouldn't really test much of the code but it's at least something. Perhaps you could post a new version with that?
Added the regression test to the new version of patch.
