Re: Invalid memory alloc

Can I change the segment size to allow more memory?
Is it a good idea?
The concerned function work only on the entire table then I can't process a part of it.
Should I split the table in multiple table and merge them after the process?

Thanks
Marc

It appears pgrouting violates the 1GB per chunk limit in the postgres backend when processing large datasets:
