Tom, do you have an idea what you might have fixed to that effect ?

Well, the company I work for has all sorts of AIX hardware, but no AIX5
yet.
I usually use a 43P 150 with one 604e CPU for development and testing,
but "borrowed" another one to test the 4 CPU hang :-)

Same here, xlc from VisualAge C++, maybe other version: 
vac.C                      5.0.1.3  COMMITTED  C for AIX Compiler

I made the experience, that gcc compiled code is somewhat slower.

No idea.  I've been fixing some portability issues in dynahash.c,
but AFAIK they only affected the pgstats collector process not backends.
Also, that breakage had existed for months...
