Hello
I have a large database and I'm trying to execute delete on a table which
has some related tables. The query fails with following error:
ERROR: out of memory
DETAIL: Failed on request of size 1048576.
I'm new to postgresql and I'm currently trying to figure out what to do by
myself. I've played with some config memory parameters, but with no luck by
now. It would be great if somebody could tell me how to solve it or give any
clues on why it happens or in which direction to search.
Here is the log:
