We have done two major changes to GIN in this release cycle: changed the data page format and made it possible to skip items without fetching all the keys ("fast scan"). gincostestimate doesn't know about either change.Did this cost estimation issue get fixed?
Nope.
If not, and if this is due for 9.5, can this be removed from the 9.4 open items list?
Removed and moved to the TODO list. It's a pity, but no-one seems to have a great idea on what to do about the cost estimation, nor interest in working on it.
