RE: [HACKERS] 64 bit PostgreSQL 8.3.6 build on AIX 5300-09-02-0849 with IBM XL C/C++ 10.1.0.1 - initdb fails (could not dump unrecognized node type: 650)

Have you determined whether the problem is optimization or 64bit ?

Well, the next thing would be running the regression tests.

Since the -qnooptimize build is not optimal, an interesting build would probably be with:
CC=xlc_r -q64 -qnoansialias
