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.
