Comment (by soroosh):
This can be done without losing any functionality by setting a limit for
count like this:
SELECT count(*) from (select id from HUGE_TABLE LIMIT 10000) as b;
Then if the raws count is more than for example 10000, SQL server stops
sequential scanning through the table and paginatior can list pages around
current page but not the last page. On my system postgreql takes 60
seconds to return count of a table with 11,000,000 raws and this is
suboptimal to wait a minute for each admin page to load.
