Обсуждение: OID, 4billion+ Rows.

I have a number of clients that retain large numbers of small
transactions.  This could easily hit 4B+ at some sites.  Most rows would
be 1k max, some may exceed that, average would be between 512bytes & 1k.

Is this feasible w/Postgres?


thanks,
 Joshua

This would be a problem at the moment.  I'm expecting to see some sort
of fix for it in 7.2, however.  The simplest fix method would require a
complete-database VACUUM at least once every billion or so transactions;
but with the nonintrusive VACUUM that we're planning for 7.2, that
doesn't seem overly onerous.
