Обсуждение: Problem wth postgresql.conf
Hello all!
Никоноров Григорий
Can anyone help me with following error: I raised max_connections from 100 to 256 and try to restart server but have next error:
FATAL: syntax error in file "/opt/PostgreSQL/8.3/data/postgresql.conf" line 108, near token "MB"
How can i fix it ?

I think you need quotes here:
shared_buffers = '128MB'

I'll bet you are using an older version of PG binaries to try and start the databases. Postgres did not recognize units like MB prior to 8.2. If you try and start an 8.3 cluster with an older binary, it will throw this error (I did this by mistake on a test cluster last week, I recognize the error). Make sure that you are using the PG 8.3 binaries. Run pg_ctl --version If that's not 8.3.x, that's your problem. -- Brad Nicholson 416-673-4106 Database Administrator, Afilias Canada Corp.
Thanks Brad!
When i start pg_ctl from postgresql v 8.3 i have this error but how i think pg_ctl used postgresql.conf from v. 8.1.4. Next thing - completely delete Postgresql v. 8.1.4 from server. Now all fine :)
Thank you all!

nope, no quotes).
I'll bet you are using an older version of PG binaries to try and start
the databases. Postgres did not recognize units like MB prior to 8.2.
If you try and start an 8.3 cluster with an older binary, it will throw
this error (I did this by mistake on a test cluster last week, I
recognize the error).
Make sure that you are using the PG 8.3 binaries. Run
pg_ctl --version
If that's not 8.3.x, that's your problem.
