Обсуждение: Unable to reload postgresql.conf without restarting
Hi,
I made some changes to postgresql.conf and I want them to take effect without having to restart the server.
I tried
select pg_reload_conf();
/usr/pgsql-9.1/bin/pg_ctl reload
but when I do 'show all', I see no changes take effect.
There settings I tried to change are:
-effective_cache_size
-work_mem
Im using posgres 9.1 on Centos Linux (amazon ec2)
Thanks

They should have been reloaded. Have you set them by role, database or tablespace?
Or even, has them been set, by mistake, twice at postgresql.conf? If so, the last one
will be used.

They should have been reloaded. Have you set them by role, database or tablespace?

I think, these parameters are duplicated in postgresql.conf file. Can you check whether the same parameters are exits in bottom of the file. If so, you need to change at the bottom(or comment them).

That is quite odd. Can you show us the commands and the postgresql.conf
line you are changing?

Also make sure you're changing the right postgresql.conf, that the server wasn't started with a different one than you think. -- Scott Ribe scott_ribe@elevated-dev.com http://www.elevated-dev.com/ (303) 722-0567 voice

Yep. The config_file parameter can be used to check it:
SHOW config_file;

Check your server log for any report of a syntax error in your .conf file. If there is one, that will prevent the changes being loaded. pg_reload_conf() will still return 't' and you'll be unaware of the problem > I tried? > > select pg_reload_conf(); > /usr/pgsql-9.1/bin/pg_ctl reload > > but when I do 'show all', I see no changes take effect.? > > There settings I tried to change are: > -effective_cache_size? > -work_mem > > Im using posgres 9.1 on Centos Linux (amazon ec2) > > Thanks > -- Jerry Sievers Postgres DBA/Development Consulting e: postgres.consulting@comcast.net p: 312.241.7800

Can you try just with SET command and verify the behavior, as these parameters are USERSET parameters, so no need to change config file and reload or restart. With Regards, Amit Kapila.
