Re: Insufficient memory for this operation.

Hi Grag,
thank you, I realized the problem. I treated these values as per server
values not per connection.
It's now working with 20 or more concurrent connections well.

bye,

You can lower this to 10,000 or even lower.

That's 16M per connection with a maximum of 100 connections. So that's up to
1.6G that postgres has been told it can grab. It's unlikely it would grab it
all at once though unless lots of connections are running queries with big
sorts.
