Tuning of postgres is done via the postgresql.conf file.
Settings based on available RAM
shared_buffers=1/4 of the available memory
effective_cache_size = 1/2 of available memory
Standard Settings
autovacuum_max_workers = 1 checkpoint_completion_target = 0.9 checkpoint_segments = 32 log_min_duration_statement = 5000 synchronous_commit = off work_mem = 10MB wal_buffers= 10MB commit_delay 10 max_locks_per_transaction=3000
Example for a server with 16GB of RAM
effective_cache_size = 8GB shared_buffers = 4000MB
