Update: I discovered that I can get the regression tests to fail (even on mainstream 64-bit platforms) by MAXALIGN()'ing the expression that we assign to state->maxpostingsize at the top of _bt_dedup_pass(). This is surprising; it contradicts existing comments that explain that the existing max is 1/6 of a page by choice, to get better space utilization than the more natural cap of 1/3 of a page. It now looks like that might have actually been strictly necessary, all along. -- Peter Geoghegan
