Is this a bulk insert?  Are you wrapping your statements within a transaction(s)?
How many columns in the table?  What do the table statistics look like?

In my opinion it depends on the application, the priority of the application
and whether or not it is a commercially sold product, but depending on your
needs you might want to consider having a 3rd party vendor who has expertise
in this process review and help tune the application.  One vendor that I
know does this is EnterpriseDB.  I've worked with other SQL engines and have
a lot of experience tuning queries in a couple of the environments but
PostGresql isn't one of them.  Having an experienced DBA review your system
can make the difference between night and day.
