I'm just digging a little bit in PostgreSQL internals and I found the
following thing. Shouldn't the reltuples field in pg_class contain the
real number of tuples? It is always a little bit to low ...
irc=# SELECT reltuples FROM pg_class WHERE relname = 'events';
reltuples
-----------
188
(1 row)
irc=# SELECT COUNT(*) FROM events;
count
-------
195
(1 row)
This annoys me a little bit as I can do
SELECT reltuples FROM pg_class WHERE relname = $1;
from plpgsql, but not
SELECT COUNT(*) FROM $1;
