Subject: Optimizing for writes. Data integrity not critical

Hi,
I am using postgresql in small (almost trivial) application in which I
pull some data out of a Cobol C/ISAM file and write it into a pgsl
table. My users can then use the data however they want by interfacing
to the data from OpenOffice.org.
The amount of data written is about 60MB and takes a few minutes on a
1200Mhz Athlon with a single 60MB IDE drive running Fedora Core 3 with
pgsql 7.4.7. I'd like to speed up the DB writes a bit if possible.
Data integrity is not at all critical as the database gets dropped,
created, and populated immediately before each use. Filesystem is ext3,
data=ordered and I need to keep it that way as there is other data in
the filesystem that I do care about. I have not done any tuning in the
config file yet, and was wondering what things would likely speed up
writes in this situation.
I'm doing the writes individually. Is there a better way? Combining
them all into a transaction or something?
Thanks,
Steve Bergman
