Preventing work on new indexes by non-committers has meant that Bitmap
indexes, which first came out in 2005 have not been usable with
Postgres. That forced people *away* from Postgres towards Bizgres. Lack
of Bitmap indexes is a huge issue for many people. It's 2009 now and it
seems probable that without this patch it will be 2010 at least before
they see BMIs, and later still before they see other index types.
No-one is preventing anyone from working on bitmap indexes.
Bitmap indexes required other backend changes, in addition to the rmgr
changes. This rmgr plugin patch is *not* sufficient to enable bitmap
indexes to live as a plugin.
This patch does *not* bring us any closer to having bitmap indexes.
Don't raise false hopes.
