thanks for your reply, yes i did not have any postgis installation. i'm a little bit confused right and i really need some help.. this is my case: i have pg8.3.2 running with postgis 1.3.x, i'm willing to upgrade to pg9.2.4 using the pg_upgrade utility, now the problem is that apparently i need to upgrade also to postgis 2.0.3 (so that's to upgrade in once) i read the instruction in postgis webpage and i need to do a hard_upgrade... which is a dump and restore. so i don't know how to proceed... install pg9.2.4 -> upgrade pg8.3.2 to pg 9.2.4-> then postgis??? or install pg9.2.4->install postgis 2.0.3 in the pg9.2.4 -> (pg_upgrade of the DB on pg8.3 to 9.2.4) OR hard_upgrade using the postgis scripts? thanks -- View this message in context: http://postgresql.1045698.n5.nabble.com/PG-UPGRADE-major-issue-tp5759906p5760168.html Sent from the PostgreSQL - admin mailing list archive at Nabble.com. -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
