Re: Index File growing big.

I remember this is your second posting for the same problem.

I hope you are aware that postgres can manage multiple databases that
lie in different partitions.

If its feasible for you you may think of moving the *big* tables in another
database which can be initialised in another partition. it depends on ur app
design as you will have to create a new db connection.

another possibility is to buy a new bigger hdd ofcourse ;-)
and migrate the data.

also i think the <tableid>.1 or <tableid>.2 are extensions of the
datafile not index files. index files have seperate id of their own.
pg_class have that id in relfilenode.

in case i am getting the problem wrong , my query is have you relocated the
index files also and created the symlinks ? (using ln -s)

Also 7.2.1 is too old an version to use in 7.2.x series 7.2.4 is latest
and in 7.3.x 7.3.2 is latest.
