[postgis-users] installing 2 versions of postgis

[Paragon Corporation]

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

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
