[postgis-users] postgres and postgis upgrade

Thu Jul 4 15:07:32 PDT 2013

The postgis.sql is a part of the restore process. Because you'll make 
hard upgrade of PostGIS, you have to use Perl script postgis_restore.pl. 
This script removes old PostGIS functions from your backup and installs 
the new ones in the new database. Then, you have to give the path of 
postgis.sql (or lwpostgis.sql) when you call postgis_restore.pl on 
command line.

I'm not really fan of the new procedure using "CREATE EXTENSION 
postgis". It's an automatic process enabled in PostgreSQL 9.1 and more. 
With this procedure, you have to use PostGIS who is embedded with 
PostgreSQL package. I encountered earlier some errors when I tried to 
install PostGIS using this procedure on a Windows box. But, using the 
old procedure I described above, I had the complete control of the 
installation and I always got a functionnal database, even with 
PostgreSQL 9.2.
