Hi,
we install Postgres on alpha axp 3000/500 running osf/1 v2.1.
Installation was ok. We found problems using copy command with a ascii file
which dimension is 89373089 bytes. After two houres the copy aborts
with the message "FATAL 1:Feb 4 22:54:39:palloc failure: memory exhausted".
Then we use the command vacuum on the same database and also after two
houres vacuum abborts with the same error message.
Do you have any idea about?? May be is shared memory problem??
Does it is normal that these commands take this long time to run?
Thanks,
Regards,....David

you're likely hitting process virtual memory limits (based on
available swap space). each copy command runs in one transaction and
some types of memory are only freed between transactions.
i would try splitting the file into smaller chunks and loading them
with separate copy commands.
