There is a loop of recursive query. It runs at a point where it stops.
This error turned up.- ERROR: invalid memory alloc request size 1073741824
Can anyone provide pointers how to solve this problem or work around?
Regards,
David

Quite difficult without any code snippet (or even which language) but
you've requested a single block of memory that is larger than the
maximum allowed. That number (1,073,741,824) is 2^30 .

Might be a bug, but with no details it's impossible to tell.

For both recursive and non-recursive queries its possible to write a
query with mistakes in it that will run for a long time or run out of
resources.
Find the mistakes in your query by simplifying it.
