So I see no evidence for a slowdown on pgbench's SELECT queries.
Anybody else want to check performance on simple scan/join queries?


I did your tests with configure --enable-depend and pgbench -i -s 100 and slightly tweaked postgresql.conf, on notebook with CPU i7-3520M (2 cores + 2 HT), FreeBSD 10.2.

pgbench -c 4 -j 4 -P 1 -T 60 -S
HEAD         35834 tps avg (35825/35828/35808/35844/35865)
Patched HEAD 35529 tps avg (35516/35561/35527/35534/35510)

~1% slowdown. I can live with that.
