7,643,966 files taking up 7.265 T of space on tape.

I'm intrigued about this batch file. Where is it and how big is it? I
can increase the size of /var, or move the postgresql database mount
point, but it is difficult to know how much size it may require.

I turned off spooling and set the Spool Attributes directive to no and
reran the backup. The backup job completes but the database insert bails
out.
clwbackup-dir JobId 8: Fatal error: sql_create.c:894 Fill File table
Query failed: INSERT INTO File (FileIndex, JobId, PathId, FilenameId,
LStat, MD5)SELECT batch.FileIndex, bat ch.JobId, Path.PathId,

h.Path = Path.Path) JOIN Filename ON (batch.Name = Filename.Name):
ERR=ERROR: could not write to hash-join temporary file: No space left
on device
I don't understand why bacula isn't writing to the database
continuously. Why is a batch file needed?
