PostgreSQL 7.3.3 and Intel C compiler

This week I have done some performance tuning at a customer's office. We 
have beaten (demoralized) MS SQL and DB2 in serializable mode and DB2 in 
any transaction isolation level :).

By the way: In case of very simple statements SERIALIZABLE is about 3 
times faster than READ COMMITTED. I expected it to be faster but I did 
not expect this difference.

We have used Peter's fix which makes it possible to compile PostgreSQL 
with Intel's C compiler. PostgreSQL built nicely (just some nasty 
warnings). We have tries to run our benchmark (mostly simple statements 
and cursor work) on this version of PostgreSQL but the database cluster 
corrupted almost instantly.  Although PostgreSQL compiled nicely we 
could not get the system running without corrupting something.
Maybe this behaviour should be varified by somebody else and documented 
somewhere (maybe a FAQ?).
Regards,
    Hans
