I just found out about pgtune and am trying it out on my server.
I have 2.5 questions:
1) Are these settings the maximum that the server will handle, if it is strictly dedicated to postgresql? Meaning if I am running other stuff on the server as well, this would be a bad idea.
1a) If I have some intense plpython stored procedures, do they run in the postgresql memory space (ie using the memory settings from the postgresql.conf, or do they run under their own memory space and then I would have to take that into account when allocating postgresql memory?
2) If it sets my max_connections to 80 and would like to set it at 300, what would be the appropriate setting to lower at its expense?
Sim
Look at the options available in pgtune
-M TOTALMEMORY, --memory=TOTALMEMORY Total system memory, will attempt to detect if unspecified -T DBTYPE, --type=DBTYPE Database type, defaults to Mixed, valid options are DW, OLTP, Web, Mixed, Desktop -c CONNECTIONS, --connections=CONNECTIONS Maximum number of expected connections, default depends on database type
For question 1, you can set the type of server you want. For question 2, you can pass the -c parameter and it would adjust the other parameters. Not sure of 1a though.
