f some-boring-process is running in your current bash session:

  1. halt it with ctrl-z to give you the bash prompt
  2. put it in the background with bg
  3. note the job number, or use the jobs command
  4. detach the process from this bash session with disown -h %1 (substitute the actual job number there).

or use screen or tmux

Configuration calculator for PostgreSQL

Posted on by

http://pgtune.leopard.in.ua/

PGTune calculate configuration for PostgreSQL based on the maximum performance for a given hardware configuration. It isn’t a silver bullet for the optimization settings of PostgreSQL. Many settings depend not only on the hardware configuration, but also on the size of the database, the number of clients and the complexity of queries, so that optimally configure the database can only be given all these parameters.
