Re: [PERFORM] Connections "Startup"

Postgres is designed in this way. It can handle such problem by adopting the following steps:
1.Increase the kernal level parameters:shmmax and shmallexample for 2GB RAM size for postgres processing is below
vi /etc/sysctl.confkernel.shmmax = 2147483648
kernel.shmall = 2883584

similar way you increase the configuration paramater for half of RAM size of your machine.

2. Edit your postgresql.conf file following settings:
a. Increase the number of connection parameter.
 Connection = 500
b.Effective_cache_size = 2GB
c. Shared_memory = 500MB

I'm sure Pavel meant 9.1.19, not 9.2.19.

In any case, be aware that 9.1 goes end of life next year. You should
start planning on a major version upgrade now if you haven't already.
9.5 should release in January so you might want to wait for that version.
