Just wondering...if a query is "waiting", what is it waiting for? Is
this only for locks, or can it be for disk, or a memory buffer? (If
there is a description of the meaning of things in pg_stat_activity
and it's relatives, I'd love a pointer, 'cause I can't seem to find
it.)

Only locks.
There isn't much at the moment. 9.2 docs will be better in that regard.
See
<a href="http://www.postgresql.org/docs/9.2/static/monitoring-stats.html#PG-STAT-ACTIVITY-VIEW" title="http://www.postgresql.org/docs/9.2/static/monitoring-stats.html#PG-STAT-ACTIVITY-VIEW">http://www.postgresql.org/docs/9.2/static/monitoring-stats.html#PG-STAT-...</a> for example (but be careful that some columns of pg_stat_activity change in 9.2).
