Hi, check for blocksize (8k) as factor. 8k*131072=1G regards Thomas Am 29.01.19 um 13:32 schrieb Bob Jolliffe:
Excuse me if this is a silly question. I am trying to fiddle with shared_buffers setting on postgresql 10.6 on ubuntu 18.04 server. I have this at bottom of my config file: shared_buffers = 1GB Yet when I check the setting from pg_setting I see something quite different: postgres=# SELECT name, setting FROM pg_settings where name = 'shared_buffers'; name | setting ----------------+--------- shared_buffers | 131072 Is this a question of units? It looks like 128M. Note when I change the setting to 2GB in conf file I see 262144 from pg_setting. I am now unsure what the actual shared_buffers allocation is. I cant see anything in the docs which tells me how to interpret the integer. Any clarification welcome. Regards Bob
