You can find out exactly what you're waiting for by correlating this to the
pg_locks table.

  Grab the 'procpid' of your waiting query and run:

  select * from pg_locks where pid=<thepid> and granted='f';

  Notice, in the pg_locks table, the logic works slightly different... if
you're 'waiting' (pg_stat_activity), then you haven't been 'granted'
(pg_locks).


As far as documentation:
