| pgtune | PostgreSQL config tuner | Mehr ... | 
 pgtune works by taking an existing postgresql.conf file as an input,  making changes to it based on the amount of RAM in your server and  suggested workload, and output a new file.  .  pgtune will add a set of configuration values at the end of the  output file.  .  pgtune will set values for variables like maintenance_work_mem,  effective_cache_size, work_mem, wal_buffers, checkpoint_segments,  shared_buffers or max_connections |
