Hi,
little question:
when is WAITING in PG_STATS_ACTIVITYset to TRUE ?
When this connection is waiting on a lock , or are there any other
reasons, waiting on another resource ?
TIA

Maybe consider using LVM snapshots in conjunction with rdiff-backup as
an option well. Simple to setup, simple to manage, no downtime, very
space efficient.

Btw, related to one my earlier questions: where can I see how many
connections are being made to the DB, what was the maximum number
attempted at any given time, and so on? The connections related info.
Thanks!

Hi,
When I started with MySQL I exploited their "bug" with timestamp
fields and always had a entered and updated field on my tables.
My question, is this interesting information enough to save on the
