Here's another thing that I think it would be good to fix in 8.0.
We've had numerous complaints before about RI constraints not firing

Folks,
I was just noticing that pg_stat_activity is truncating queries which are
logged to it at about 150 chars. I can't think of any good reason for this.
Is there one?

There is good reason to limit the packet size, but to a kilobyte or so.

So what is the thinking of HACKERS?
Does it make sense to include nothing and rather allow each
distribution to support its own?
Or should each distribution known to support postgres be invited to
submit the relevant script for inclusion? And, if so, should this be a

It will have to re-examine the tail of the main list, as

shouldn't be: the costs of updating N index entries instead of just one
tuple entry, the potent
