Large Dump Files

From

Hi.

I am running postgresql 7.1 on Red Hat Linux, kernel
build 2.4.2-2.  I am in the process of updating
postresql to the latest version.

When I dump my database using all the compressions
tricks in:
http://www.us.postgresql.org/users-lounge/docs/7.2/postgres/backup.html#BACKUP-DUMP-LARGE

my dump file is still over 2gigs and thus the dump
fails.  We have a large amount of BLOB data in the
database.

I am wondering:

will cat filename* | psql dbname work if my dump file
has large binary objects in it?

If not, does anyone have experience getting Red Hat to
deal with large files.  I can find no documentation
that deals with large files for the kernel build have.

Thanks.

Mike Baker

Mike,

   Are you sure that 'split' won't work? It is specifically designed
to break apart your files into smaller chunks:


pg_dump dbname | split -b 1000m - filename

Reload with

createdb dbname
cat filename* | psql dbname
