Re: Swapping on Solaris

po and pi are relatively low, but do pick up when there's an increase in
activity. I am seeing a lot of "minor faults", though. vmstat -S 5 reports

[9:38am]# vmstat -S 5

494 in faults
1147 sy faults

Generally faults are a bad thing. Is that the case here?

Indeed.
If you DO run into trouble after giving Postgres more RAM, use the vmstat
command.
You can use this command like "vmstat 10". (ignore the first line)
Keep an eye on the "pi" and "po" parameters. (kilobytes paged in and out)
