You'll need to reinstall the old executables. If you put the new
executables in the same directories, it's not going to be easy to
run both in parallel. If you didn't, then you just need to start
the old postmaster using a different port number.
I tried to get 8.3.11 ready again:
# Problems with timezone on startup (Default not found)
./configure --with-system-tzdata=/usr/share
cp ./src/backend/postgres /bin/postgres-8.3.11
su -l postgres -c "/bin/postgres-8.3.11 -p 54321 -D
/var/lib/pgsql-old/data &" >> /var/lib/pgsql-old/pgstartup.log 2>&1 < /dev/null
Problem is that PostgreSQL doesn't listen and take much CPU and also disk
I/O. 8.3 was shut down cleanly. 8.4 runs in parallel. Are there any
problems with shared buffer conflicts?
PID USER PR NI VIRT SWAP RES CODE DATA SHR S %CPU %MEM TIME+ COMMAND

Any ideas?
Thnx.
Ciao,
Gerhard
