PostgreSQL Database Maintenance

The default configuration of PostgreSQL is set up for small servers. For a database with high volume of data and queries running on a powerful server, it is necessary to make some configuration changes. We recommend that you significantly increase the value of the shared_buffers and work_mem parameters which indicate the maximum amount of memory to be used for some operations. You can use the pgtune utility to find basic indications about the values to be used depending on the hardware configuration.
