I am currently searching some resources, why and where the PostgreSQL
GEQO-Engine improves large join queries. The theoretical background is
clear, but i need some real life szenarios, where the GEQO-Engine beats
other solutions. Have anyone made such a comparison, or have experiences
which szenarios, where the GEQO has improved the query plan generation
in contrast to "traditional" solutions? This will be very helpful (and
interesting) ....
Thanks in advance,
Bernd
