If you have an older PostGIS enabled database on your desktop or hosted elsewhere, we can upgrade your PostGIS.
To do so, take an export (pg_dump) of your database using:
pg_dump -Fc -O mydb > mydb.dump (where 'mydb' is the name of your database.
This will create a dump file in Custom format (-Fc) without owner specified (-O).
We can import your dump file for you using the postgis_restore.pl tool
