-7 Edit your PosgreSQL.conf file in the SQL 8.x/data folder.
Do not use the Tuning Wizard. On some systems it will make changes to the postgresql.conf it shouldn't, resulting in being unable to connect to the database!
If you experience this problem--> simply go to the 8.4/data folder, and delete postgresql.conf, and rename the backup postgresql.conf.2009(data xxxxxxxx) back to "postgresql.conf" and reboot.
Recommended changes:
shared_buffers = MB (set this to 20% of your system memory, but not more than 1000 MB.... round it off to 128 MB, 256 MB, 512 MB or 768 MB)
effective_cache_size = MB (set this to 2x the size of the shared_buffers)
- what do we edit the posgresql.conf file to??? Im not using the tuning wizard as stated above, but what do we edit the file to? I cant seem to open this file also.
