Postgres Server Settings

Postgres has hundreds of settings in its configuration. Nearly all of them have defaults appropriate to most of us most of the time. Here's a few you may want to consider changing.

These settings are found in the pgAdmin app menu Tools > Server Configuration > postgresql.conf.

• superuser_reserved_connections

Sets aside a few of maximum number of connections for use only by the Postgres superuser, usually named 'postgres'. Without this setting, if your server reaches its limit, you will not be able to logon as an administrator. That's not good, so turn this on and use at least the default of 3 connection slots.
