Hello

I also studies how to improve performances on big tables.
Like you , I don't know how to improve without index. It's the only way
I found .
I find postgresql is fast on small table but I got real performance
problem when increases the number of rows
Do anyone know if  there is specific postgresql tuning parameters in
.conf file for big tables ?

max_fsm_pages ?
max_fsm_relations ?
