Thanks Vadim!
This patch does help.
The simple join still uses two sequential scans though.
Is your tip regarding single-key vs. multi-key-indices still valid?
I don't see any performance difference between these two.
BTW: Has the spinlock code, that was discussed some days ago, made it
into 6.3.1.?
Ciao
