  ================== ** Postgis Upgrade Notice ** ===================

  If you are a user from a old version of Postgis (0.9.1 or older), 
  make a backup from your databases before continue !

  If you need to backup your data, press CTRL-C now !

  ======================= GEOS Support Notice =======================
  In order to use the GEOS support, you may need to specially compile
  your version of PostgreSQL to link the C++ runtime library.
  To do this, invoke the PostgreSQL Makefile script this way:

  on csh shell:

  setenv LDFLAGS -lstdc++
  make

  on sh or bash shell:

  export LDFLAGS=-lstdc++
  make

  The initial LDFLAGS variable is passed through to the Makefile and
  adds the C++ library to the linking stage.

  ===================================================================
