Download postgres database

#If you don't have postgres, download it, make sure to use the stackbuilder program to download postgis.
# open a shell with command CMD
# Move to the place where you have downloaded the file using the following command
  cd c:/path/to/my/folder
# note psql must be accessible, in windows you can add the path to the postgres 
#bin folder, otherwise you need to add the full path to the postgres bin folder see  link to instructions below    
#below I assume that the user you are using to postgres   
createdb -U postgres diaspara
psql -U postgres diaspara
# this will open a command with # where you can launch the following SQL command
CREATE EXTENSION postgis;
# You will need this because we only restore part of the database : the schema corresponding to different locations.
# Type \q to quit the psql program.

Now you will have saved the files in the c:/path/to/my/folder location where you are currently working.
You need to use pg_restore to restore the files, for instance if you want to use h_med_central.pgc

pg_restore -U postgres -f h_med_central.pgc 

Download Parquet format 

You can use the files straight from R or Qgis. To use with R you will need Arrow and DuckDB packages.
