Hi,
I was running a CLUSTER on a big database (approx. 8G) and I didn't anticipate the diskspace usage, so I ran out of diskspace. This is on PostgreSQL 7.4.6. The backend crashed with the following log messages:
2005-01-15 15:17:46 [30605] PANIC: PANIC: could not write to file "/var/lib/pgsql/data/pg_xlog/xlogtemp.30605": Geen ruimte over op apparaat
STATEMENT: CLUSTER;
2005-01-15 15:17:46 [11245] LOG: server process (PID 30605) was terminated by signal 6

2005-01-15 15:17:46 [3378] WARNING: terminating connection because of crash of another server process
DETAIL: The postmaster has commanded this server process to roll back the current transaction and exit, because another server process exited abnormally and possibly corrupted shared memory.
HINT: In a moment you should be able to reconnect to the database and repeat your command.

The database is running nice again, but I have the feeling I lost some diskspace... I suspected a temp file, so I stopped the postmaster, looked in /var/lib/pgsql/data/base/17142/pgsql_tmp, found one file and deleted it. But now I still have 1G less available diskspace than before the CLUSTER.
Where should I look next? I would like the diskspace back :-)
Thanks, Sander.
