Postgres table with geographic data - migration commands

 First let's export a table to the file system:

pg_dump --host localhost --port 5432 --username mypgusername --format plain --verbose --file /var/lib/pgsql/stations.sql --table mypgschamename.mypgtablename mydatabasename

Now we have a sql file on filesystem - ready to be migrated.

We can do that even for a remote PG server:

psql -h -p 5432 -d mydbname -U myusername -W -f stations.sql

After putting  in the password for the remote server the restore takes place over the wire.

On WAN network it might be slow and can disconnect occasionally - I'd say several hundred of MB table still can easily be restored like this.

Our new website layout is now trying to correspond to this endeavour. So if you like to see what we are up to these days please visit
