But the problem with just logging stuff is it's not a monitoring
solution. Granted, it's better than nothing, but in a production
environment I'd like to have some way to monitor temp file
usage/utilization over time. AFAIK dtrace would provide that capability,
thought I don't think it'd be unreasonable to have our own counter as
well. Perhaps add temp_usage_count and temp_usage_size to
pg_stat_database (number of times something spilled to disk and total
size, respectively).
