I played with the query a little bit. In a nutshell, the performance is
nothing short of horrible. 27:01 CPU time and no results - not even one
record inserted into the new table.
The same query completes in 5 seconds on MS Access.
There must be a way to optimize my query so it runs in some sensible way on
postgres??
