Comment(by strk):

 The library is there. If I drop it the segfault goes away so this is
 clearly a function in postgis-1.5 library segfaulting. It's puzzling that
 calling the offending select again a second time doesn't segfault. But I
 guess that's what you get when you access arbitrary memory.
 I'm lucky to get a segfault first time.

 I'll fix the upgrade script to properly skip those functions but still I'm
 curious about _why_
 geography_typmod_dims is triggered at all. Maybe we're also failing to
 drop a TYPE or we reference geography_typmod_dims from the GEOMETRY type
 definition
