A while back, we discussed using pgAdmin pgScript as a quicky way for
running a repetitive update script where you want each loop to commit right away. Since stored functions have to commit as a whole, you can't use stored functions alone for this kind of processing.
If you are using the psql client packaged with PostgreSQL 9.3 or above,
then you can take advantage of the \watch command that was introduced in that version of psql. We'll demonstrate that
by doing a batch geocoding exercise with PostGIS tiger geocoder and also revise our example from the prior article to use the more efficient and terser LATERAL construct introduced in PostgreSQL 9.3.
