[postgis-users] Upgrading PostGIS

[James David Smith]

Hi all,

Could someone point me towards some instructions for upgrading my
PostGIS version please? I interact with it using PSQL. My current
versions are below:

 PostgreSQL 9.0.4 on x86_64-unknown-linux-gnu, compiled by GCC gcc
(GCC) 4.1.2 20080704 (Red Hat 4.1.2-48), 64-bit

POSTGIS="1.5.5SVN" GEOS="3.2.0-CAPI-1.6.0" PROJ="Rel. 4.6.1, 21 August
2008" LIBXML="2.7.6" USE_STATS

Thanks

James
