Re: CentOS - PostgreSQL 9.2.13 -> 9.4

Here are the only things that I amended, all other settings are defaults.

maintenance_work_mem=2GB
checkpoint_segments=64
wal_keep_segments=128
max_prepared_transactions=10
max_wal_senders=3
wal_level=hot_standby
max_files_per_process=1000000
max_stack_depth=7MB
wal_buffers=64MB
shared_buffers=60GB
work_mem64MB

Other settings were changed and reverted again due to performance decreases.

I also dropped shared_buffers down to 32GB, TPS dropped further.
