Hi

I'm currently upgrading a Posgresql 7.3.2 database to a
8.1.<something-good>

I'd run pg_dump | gzip > sqldump.gz  on the old system. That took about
30 hours and gave me an 90GB zipped file. Running
cat sqldump.gz | gunzip | psql
into the 8.1 database seems to take about the same time. Are there
any tricks I can use to speed this dump+restore process up?

The database contains quite alot of BLOB, thus the size.

Jesper
