Judging from your examples it's got something to do with the partial
index WHERE clause.  What PG version is this exactly?  If you leave out
different parts of the WHERE, does it still crash?  Does the crash
happen immediately after you give the command, or does it run for
awhile?  It might be worth getting a stack trace from the failure
(best way is to attach to the running backend with gdb, provoke the
crash, and do "bt" --- search for "gdb" in the archives if you need
details).
