Re: Raw disk space used

Thanks so much fro the info.

I've done as you suggested and I've got the correct directories. I have a second question now. There are forty-four numeric entries in the directory for the first databases that I looked at. The database in question has only eight tables. There are eight tables that have recent dates. Do I need the total of all the files or just the eight that appear to be the tables that are being updated?

Thanks again,
Carol

My user keeps clammering for this figure.

Sure, you can identify the database via "select oid, * from
pg_catalog.pg_database;"

Then you should be able to head to $PGDATA (where ever the database
data lives), and run "du", and search for the directory whose name is
the "oid" value for the database that you wanted to analyze.

If users are using tablespaces, then tables can live in
user-controlled places, which would make it rather more complex to do
this analysis, but if they have kept to the simpler approach of just
letting data fall where it will, this should do the trick...
