I hate to point this out, but "TIP 4" is getting a bit old and the 6
tips that we throw out to probably about 40K people about 1-200 times
a day have probably reached saturation. Without looking at the
archives, I bet anyone a shot of good scotch that, it's probably
pretty infrequent that people don't kill -9 their postmasters.

Any chance we could flush out the TIPs at the bottom to include,
"VACUUM ANALYZE your database regularly," or "When reporting a
problem, include the output from EXPLAIN [query]," or "ANALYZE tables
before examining the output from an EXPLAIN [query]," or "Visit [url]
for a tutorial on (schemas|triggers|views)."
