26451	extend Paginator to support infinite pagination and postgres estimated count	Denis Cornehl	Denis Cornehl	"We often have problems with bigger tables and slow {{{count(*)}}} performance. 

depending on the use-case there are two ways to improve the situation
* just work without count, if you never show the page-count. Then the paginator can just return empty results if the end is near. 
* use rough estimations for the page-count, perhaps with some security margin. For example PostgreSQL supports this by using {{EXPLAIN}}, based on the table statistics. 

I want to 
* extend the paginator to support both (infinite and estimate)
* provide an option for {{ModelAdmin}} that let's you use the estimation-paginator. 
* or perhaps even support the infinite-paginator, this would also include interface changes to the pagination. "	New feature	new	Core (Other)	1.9	Normal			Johannes Maron	Unreviewed	0	0	0	0	0	0
