Many Thanks for all the replies.
The conversion project to version 8 is still in progress, hence we are still
experiencing problems on a version that's not supported. That's an honest
answer I can give. The thing is it's frustrating to not to have a source of
support as we still have to give support on this version 7.3.4
There is a script that runs once a month which reindex, vacuum full verborse
and vacuum analyze :
Small picture inside the script:
echo "VACUUMING TABLE ${table} " >>$log 2>>$log
/usr/local/pgsql/bin/psql -U $dbuser -h localhost ${db} -tc "REINDEX
TABLE ${table}" >>$log 2>>$log
/usr/local/pgsql/bin/psql -U $dbuser -h localhost ${db} -tc "VACUUM
FULL VERBOSE ${table}" >>$log 2>>$log
/usr/local/pgsql/bin/psql -U $dbuser -h localhost ${db} -tc "VACUUM
ANALYZE ${table}" >>$log 2>>$log
Dumping and restoring the database doesn't decrease the space
There is nothing set in the postgresql.conf file that has to do with vacuum
analyze.
If we could have a way to reduce the space in
/usr/local/pgsql/data/base/95186722 directory we would be sorted

OK - what version of postgres would be a good starting question...
But, at a guess, I'd say you have a fair amount of table churn, and that
you're probably due running a VACUUM FULL over the database that is
using the most space, it may fail, but if it does it should tell you
what bit of config you'll need to change to make it work.
The other possible usage of lots of space is indexes on the database
tables, these are not included in the dump, and so the size of the dump
doesn't accurately reflect the size of the on disc data.
Hope that gives you somewhere to start from.
Thanks,
