I've read article by Theodore Jonhnson
"Performance Measurements of Compressed Bitmap Indices"
http://www.informatik.uni-trier.de/~ley/db/conf/vldb/Johnson99.html
and is wondering if there are plans to implement bitmap indices
in postgres. As it stated in the article these indices could speedup
join operations and decision support queries.
Regards,
Oleg
