RAM/CPU running queries

Hi everybody,

I would like to know if its possible to do a "snapshot" (like a print memory or cpu for example) of runnning queries in postgresql.

I'm using pg_activity (https: // github.com / julmon / pg_activity) and this tool is displaying CPU and RAM stats per queries.

Howewer, i've sent a message to the publisher (Julien Tachoires) who informed me that he had already several requests about this feature but at the moment it's not possible.

If you have suggestions or ideas about this, let me know, thanks.

Regards.
