[postgis-users] RE : Trying to restore a .backup file

[Alain Benard]

Hi,
i think the problem is with a backup / restore from an old postgis 
version to a new postgis version. The postgis function are differents 
between 2 version and you cannot juste restore the database even if you 
don't install the extension (the definition of the old functions are not 
in the executable file from the new installation). In the Postgis 
documentation you can find a perl tools wich analyze a backup file and 
delete what can be in conflict before process the pg_restore. The 
chapter '2.9.2. Hard upgrade' in the folowwing page is probably the 
solution :
http://www.postgis.org/documentation/manual-svn/postgis_installation.html#hard_upgrade
have a nice day.
Alain.
