I would use normal pg_dump and pg_restore for the DBs and not utils/postgis_restore.pl. Also, AFTER I backup all databases and everything else, you could try to upgrade Postgis without upgrading PostgreSQL by buliding from source e.g. http://trac.osgeo.org/postgis/wiki/UsersWikiPostGIS21Ubuntu1304src. There it says that Postgis 2.1 could be used with PostgreSQL 9.1. This will give you access to Postgis 2.1 features without reinstalling everything. Of course normally I would not upgrade if this is an 1-2 years project, unless I 100% need Postgis 2.1 features not present in 1.5. -- View this message in context: http://postgresql.1045698.n5.nabble.com/Hard-upgrade-everything-tp5790801p5790811.html Sent from the PostgreSQL - general mailing list archive at Nabble.com. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
