[postgis-users] installing 2 versions of postgis

[Paragon Corporation]

Yes you can have 2 postgis templates (1.5, 2.0).  I don't for PostGIS 2.0 at
the moment because it's in major flux so requires rebuilding the template
pretty much each time.
 
For PostGIS 1.5 its fine.
 
Yap what you are saying sounds about right.

Thanks Regina,

I am about to try it.

 

Is it possible to have,using this procedure, under the same database, two
templates (template_postgis20 and template_postgis15), and then create a new
database with template_postgis15 as the template;

 

Or is it best to create a new database directly with 1.5 version?

 

As I understand it, I am going to 

-          backup the newer versions of proj.dll and geos*.dll, run the bat
script and then copy back the newer geos*.dll and proj.dll, and delete the
old geos*.dll that the 1.5 bat script would copy over

-          I was going to comment out the postgisgui copy in the bat script
because that is already installed during the 2.0 installation

 

Does that sound right to you?

Thanks,

Vishal

Vishal,

 

You just need to install the postgis scripts for 1.5 in the database (and
copy over the postgis-1.5.dll etc in the lib folder).

 

Both can coexist on same cluster as long as they are in different databases.

 

If you look at the zip download packages we have the batch file will install
the postgis in the specified database

PostGIS 1.5: http://www.postgis.org/download/windows/#windbinaries

PostGIS 2.0:
http://www.postgis.org/download/windows/experimental.php#PostGIS_2_0_0

 

The only thing to keep in mind is currently they will share the same GEOS
and Proj.  The PostGIS 2.0 has a slightly newer GEOS (geos 3.3.1 branch and
I think the PostGIS 1.5.3 we packaged GEOS 3.3.0).  Note: 1.5.2 we packaged
with GEOS 3.2  which won't work with PostGIS 2.0.

 

If you plan to run both, you should use the GEOS in PostGIS 2.0.0 since the
PostGIS 2.0.0 GEOS will is  backward compatible with 1.5.2 and 1.5.3.

 

Let us know if any of this is unclear.

 

Hope that helps,

Regina

Hi all,

s-raster-on-windows/

 

My qn is how can I have postgis1.5 also installed, say in a different
database, on the same machine and database cluster? 

 

Thanks,

Vishal
