Hi,
here is a patch implementing an index recommendation advisor for
7.4.13. It consists of extensions to the planner and the catalog as
well as a command line tool pg_advise in contrib. The index advisor
works as part of the EXPLAIN statement, i.e. by
set enable_indexadvisor=true;
explain select ...
you will find the recommended indexes in pg_indexadvisor afterwards.
Comments are welcome.
Best,
Kai
