After a little blip at startup, it stops using CPU. Here's a snippet of the "ps": 21966 pts/0 S 0:00 /bin/sh /usr/lib/postgresql/bin/vacuumdb temp 21971 pts/0 S 0:00 /usr/lib/postgresql/bin/psql -c VACUUM -d temp 21972 ? S 0:00 postgres: postgres temp [local] VACUUM waiting > And what are they doing --- who started them, what query was sent to > 'em, etc? Here they are- they appear to be selects via JDBC initiated by Tomcat, but I can't think of a way to find out what the actual query was (the browser sessions are gone): 18980 ? R 193:28 postgres: www-data temp 127.0.0.1 SELECT 16093 ? R 197:05 postgres: www-data temp 127.0.0.1 SELECT > If you haven't a clue, try attaching to each process with a debugger and > printing out the global variable debug_query_string. How do I do that?
