I'm having a problem with plpgsql functions leaking memory.
Your example shows absolutely no memory leak here, in either 8.3.3
or CVS HEAD.
I see the postgresql process growing from 8MB to about 400 MB during this
run...
What do you have shared_buffers set to? I think you might be getting
fooled by top's treatment of shared memory (ie, it starts to count
shared pages after the process touches them for the first time).
That's what I thought at first when I saw Marc's email. I tried his
example many times, with different values for shared_buffers. RSS column
climbs until it reaches more or less the shared_buffers configuration.
But, if I launch another psql, this process will have a much lower value
on the RSS column. Shouldn't it get the RSS at the same value, even when
the process starts ?
I'm a bit puzzled by this column, anyone has a URL where I can find more
info?
Regards.
