Hey,
I don't know if this is possible but maybe someone here
will know.
I compiled version 7.4.1 of postgres and added a specially
patched version of postgis which allows me to store and retrieve
spatial data.
I have another postgres installation (version 7.3 I think) on
another machine which has all my map data stored on it, but doesn't
have the special patched version of postgis.
The data is huge - well over 50 gigs - so theres no way I want to have
to copy all the data onto the new box. Is there any way I can point the
new installation at the tables on the old installation ??
Thanks
Colm De Barra

You can only avoid a dump and restore when upgrading in the same series (e.g. 7.3.2 -> 7.3.5) and if you use the same configuration options when building the package. If you are really asking if you can make cross database references, dblink might let you do that. I don't know if it is restricted to other databases in the same cluster or if you can connect to any database (in which case it should be usable). There have been some discussions about making upgrades smoother. I think that things might improve after 7.5.

You'll need two servers (or two clusters running on one server) -- the old one and the new one. It'll look like this: $ pg_dumpall (old database options) | psql (new database options) template1 -- Jonathan Gardner jgardner@jonathangardner.net
