I decided that it might help to list the cardinalities of the pertinent
tables:
Intsetmedia: 90,000 rows
Interaction: 26,000 rows
Set: 7,000 rows
Media: 80,000 rows

Stephan,
Hmmm ... I'm a bit confused by the new EXPLAIN output. Stefan, does
Oleg's
output show the time for *one* subplan execution, executed for 44,000
loops,
or does it show the total time? The former would make more sense given
his
query, but I'm just not sure ....
