Guide to compile and install PostGIS 2 on FreeBSD with PostgreSQL 9.2

[work in progress.]

Currently there is no PostGIS2 port, so you will have to compile directly from source.

Follow generic guide here: http://postgis.net/docs/manual-2.0/postgis_installation.html

FreeBSD specific guide:

Install/upgrade dependencies:

Check PostgreSQL installed

  pkg_info | grep sql

Upgrade to PostgreSQL 9.2 [not needed as long as you have >9.0, but as this is a development server, I moved to 9.2]

  pg_dumpall > dumpfilename.sql [have to be proper user]

  /usr/local/etc/rc.d/postgresql stop

  cd /usr/local/

  mv pgsql pgsql_dump_`date +%Y%m%d%H%M`

  pkg_delete postgresql91-contrib

  pkg_delete postgresql91-client

  pkg_delete postgresql91-server

  cd /usr/ports/databases/postgresql92-server

  make install clean [config as needed]

  repeat for contrib

[see for better instructions on upgrading: http://www.b1c1l1.com/blog/2011/01/01/upgrading-postgresql-on-freebsd/]

Upgrade PGAdmin3 to 1.16 to work with PostgreSQL 9.2

  Throws an error when port is compiled.  I took the easy way and installed the newest PBI

Use 'pkg_info |grep gdal' to check for gdal, proj4, and other dependencies

Install/upgrade as required from ports

cd /usr/ports/graphics/gdal

make install clean
.......

Download:

wget http://www.postgis.org/download/postgis-2.0.2.tar.gz

tar -xvzf postgis-2.0.2.tar.gz

cd postgis-2.0.2


Configure:

First got iconv.h configuration errors.  Tried to link to iconv work directories - no go. Use ./configure --with-... as in provided link.

Build

$ make install

Go to PGAdmin3 -> database you want the spatial extensions on -> extensions -> add new extension -> choose postgis & postgis topology


Remember to have fun!
