For this post, we will use the same setup as in Pandas to PostGIS using Psycopg2. The database connection parameters are the following
"host" : "localhost", "database" : "globaldata", "user" : "myuser", "password" : "Passw0rd"
And inside the globaldata database, there is a stations table that you can query to get the following result (using PgAdmin for instance).
# First create a local directory to store your shapefile files mkdir my_shapefiles cd my_shapefiles # Notice the correspondance between every parameter and the connection parameters above pgsql2shp -f stations.shp -h localhost -u myuser -P Passw0rd stations "select * from stations;"
If your command is successful, it should produce an output similar to mine below
Initializing... Done (postgis major version: 3). Output shape: Point Dumping: X [100 rows].
Your files should now be ready
>>> ls stations.cpg stations.dbf stations.prj stations.shp stations.shx
You can open your shapefile with any GIS client, like with QGIS for instance.
