Re: out of memory for query, partitioning & vacuuming

My work_mem setting is the default (1MB), but I'm doing a simple "select
* from schema.table" - - no joins, order by, distinct, hashes in the
statement - so I dn't think that's it.

I'm getting the error in psql, so based on what Scott said, it sounds
like there's nothing to do server side.

Thanks!

What are your work_mem settings ? Work_mem limits the amount of memory
used before using the disk. You may have a large value and a few
sessions may end up using all the available memory.

Read this on work_mem

Hi -
I'm not a particularly experienced dba, so I'm hoping this isn't a
ridiculous question.
I have a 5 GB table with lots of churn in a 14 GB database. Querying
this one table without limits has just started throwing "out of memory
for query" from multiple clients (psql, java). I'm working with the
developers to look at it from the client side, but I'm wondering if
either partitioning the table or more aggressive vacuuming of this table
would have an effect on the out of memory problem.
I'm running 8.3.5 on solaris 10.
Thanks!
