Thread: Which DB is using space.

Which DB is using space.

From

Date:
Hi all,

Below is the output from 'du -kx /|sort -rn|head'.  It's showing that
/var/lib/pgsql/data/base/46169 is using a big chunk of my disk.

How can I tell which DB this is?
What suggestions can people make to reduce the amount of disk space used by
this DB?

__BEGIN__
361365    /
282030    /var
232427    /var/lib
186879    /var/lib/pgsql
186874    /var/lib/pgsql/data
153866    /var/lib/pgsql/data/base
122399    /var/lib/pgsql/data/base/46169
40675    /lib
__END__

Sure, see contrib/oid2name.  It generates a list of oid/dbname pairs.

Also, I recommend getting oid2name from the snapshot/CVS and using that.
It has the newer readme and some changes to make the examples display
properly.  Also see the new doc section for 7.3 on disk usage:
