What does "reltuples" from pg_class represent?

Here is something that raised this question:
---------------------------------------
testdb=# select count(*) from zuser3;
count
---------
1000000
(1 row)
testdb=# select count(*) from zuser2;
count
--------
100000
(1 row)
testdb=# select count(*) from zuser1;
count
-------
1000select relname,relpages,reltuples from pg_class where relname like
'zuse%';
relname | relpages | reltuples
---------+----------+-----------
zuser2 | 10 | 1000
zuser1 | 10 | 1000
