One more note.  I added extra disk space, so I cleared that part up.

Subject: [GENERAL] recovery from out of disk space

I use PostGre 8.3 on Ubuntu.

I realized last Friday that my /opt hard disk was full. The disk was full about 2-4 hours of moderate activity. The disk  ran out of space for reasons outside of postgres
I'm really at a loss of what to do.  Does anyone have suggestions for what my next step should be.  T

More details:

When I run postgress...Postgres seems to come up...However, it is completely unresponsive to my application.  Everything just hangs.

postgres  7364  0.0  1.5 1089056 27164 ?       S    09:35   0:00 /opt/PostgreSQL/8.3/bin/postgres -D /opt/PostgreSQL/8.3/data

I also tried to run pg_dump to make a backup and that failed with the following message:
