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?
If you can have both database systems up at the same time, you could
pg_dump | psql.

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
