*** PostreSQL database install pre-requisites

********* 
Bingo postgres engine requires a lot of shared memory. 
For linux systems GGA recommends to change kernel.shmmax and kernel.shmall
The system parameters can be changed by adding the strings:

kernel.shmmax=<value>
kernel.shmall=<value>

into the /etc/sysctl.conf and launching (with the root privilegies)

 >   sysctl -p /etc/sysctl.conf

The recommended value is appr. 50% of the RAM (in bytes)

********* 
Also, there is a parameter in the postgres database configuration file (postgresql.conf):

shared_buffers=<value>

The recommended value at least 32 Mbytes:

shared_buffers=32MB
