Re: pgadmin3 and partitionned tables

all the databases of the cluster are regularly vacuumed (at least once a day), 
all the stats are up to date.

what i'm talking about is a partitionned table (8.1, with constraint 
exclusions), a 'main' table empty, and a dozen of inherited tables, which 
contain the real data. The main table contains 0 record, only the inheriting 
tables contain data. So the stats are right saying that the main table 
contains 0 record. Then, seeing that, pgadmin decides to count the record (as 
there aren't supposed to be a lot of them), but gets to read millions of 
record (the content of all the partitions).
