do these changes please look okay for a PostgreSQL 9.3 running on CentOS 6.4 server with 32 GB RAM (with Drupal 7 and few custom PHP scripts)
postgresql.conf:
shared_buffers = 4096MB
work_mem = 32MB
checkpoint_segments = 32
log_min_duration_statement = 10000
sysctl.conf:
kernel.shmmax=17179869184
kernel.shmall=4194304
pgbouncer.ini:
listen_port = 6432
unix_socket_dir = /tmp
pool_mode = session
server_reset_query = DISCARD ALL
server_check_delay = 10
max_client_conn = 600
default_pool_size = 50
I understand, that nobody can tell me the optimal settings - unless I provide full source code to everything. And if I provide "the full source code", nobody will look at it anyway.
So I am just asking, if the settings look okay or if they will waste gigabytes of RAM.
