[postgis-users] PostGIS/Mapserver Mapfile Question

[Don Drake]

I just completed an upgrade of Postgres7.4/PostGIS0.9 -->
Postgres8.0.3/PostGIS1.0.1 this week using a backup and the
postgis_restore.pl script with no real problems.

The geometry_columns table (and spatial_ref..) tables were backed up and
restored just fine for me. 

Did you backup/restore a single schema maybe?

Mark,

Awesome, that worked great.

So, what is the "correct" procedure if you want to move a table with 
geometry from database to another. Obviously, backup/restore does not do 
the "whole" thing.
