Re: [GENERAL] Optimizing projections containing unused columns

[Grzegorz Jaśkiewicz]

I just generally wanted to show, that even tho it is much smarter from
version to version, it still has this little things. I generally don't put
'is null' or 'is not null' in queries on column that is 'not null' - but it
is imo example of those little things, where postgres isn't so smart yet :)
