Hi list,
I get this error when running a SQL statement in my Java application.
ERROR: Invalid memory alloc request size 1683636507

Is Postgresql running on Windows?
What version?
I think it has something with to do with PostgreSQL
This is how I had my postgrsql.conf:
shared_buffers = 128MB
#huge_pages = try
#temp_buffers = 8MB
#max_prepared_transactions = 0
#work_mem = 6MB
work_mem = 64MB
#maintenance_work_mem = 64MB
maintenance_work_mem = 64MB
Then I changed to this postgrsql.conf:
shared_buffers = 4096MB <<<<<<<,
#huge_pages = try
#temp_buffers = 8MB
#max_prepared_transactions = 0
#work_mem = 6MB
work_mem = 256MB <<<<<<<
#maintenance_work_mem = 64MB
maintenance_work_mem = 256MB <<<<<<
And got this error instead:
Org.postgresql.util.PSQLException: AnI/O error occurred while sending to
the backend.
Failing hardware?
