tablespace.c.diff (text/x-patch) patch

Running pg_upgrade against an unmodified (the output of initdb) cluster 
on AIX is giving me  "pg_alloc: Out of memory" errors.

On some non-linux platforms (including AIX) malloc(0) returns 0.

with the attached patch to pg_upgrade I am now able to get pg_upgrade to 
convert an 8.3 database consisting of a single table to 9.0 on an AIX 
server.
