Hi,

I'm trying to install PostgreSQL 8.1.4 on my computer.
It is a Linux system with GCC 3.4.6 and GLIBC 2.3.6.
Things run on a pentium 4 (32bit) with plenty (2GB) of ram.
I can ./configure --disable-spinlocks with CFLAGS: -O2 -march=pentium4
-fprefetch-loop-arrays.

Now when I run: /usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data
I get the following errors:

postgres@muur:/tmp$ /usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

The database cluster will be initialized with locale C.

--disable-spinlocks is broken in 8.1.*. It took us a long time to
notice that, because no one in their right mind uses the option.
The performance cost is enormous.

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match

Yes, without that switch things work flawlessly.
