I have committed these changes, along with your leak patch of 5/30.

No initdb is needed --- I fixed the code instead ;-)

I bit the bullet and fixed all the places that were using "char*" where
they should have been using "Datum". This doesn't completely free GIST
from datatype assumptions: it still assumes that all datatypes it deals
with will be pass-by-reference. But it's a step forward. This means
not only a recompile but code changes for any user-supplied GIST ops.
I applied the appropriate changes to everything that's in contrib
(including your new RTREE emulation code).
