How long is "very long"? Have you seen the "Performance Tips" chapter
in the documentation, in particular the "Populating a Database" section?
http://www.postgresql.org/docs/8.0/interactive/populate.html
Are you using transactions? Wrapping a lot of INSERTs in a transaction
should be significantly faster than doing each INSERT as its own
transaction.
Have you considered using COPY instead of INSERT? COPY should be
significantly faster than INSERT for bulk loads.

See the psql documentation and your shell's documentation on how to run
a background job and redirect its output; you might also need to use
"nohup". For example, the following might work in Bourne-like shells
(bash, sh, ksh, etc.):
nohup psql -d mydb -f insert.sql > insert.log 2>&1 &
