One of the neat changes already present in the PgAdmin III 1.13dev, is the change in plugin architecture. Version 1.13 dev allows for multiple plugin*.ini files. How does this work.
Well if you have a plugins.d folder in your PgAdmin III version folder, it will read all the inis in that folder and load them as plugins.
Recall in PgAdmin III Plug-in Registration: PostGIS Shapefile and DBF Loader,
we demonstrated how to load the PostGIS shapefile and dbf loader as a plugin in PgAdmin III, well this time we will demonstrate how to do it using PgAdmin version 1.13. Better yet, we'll show you the new and improved
PgAdmin III Shapefile and DBF Loader in the works for PostGIS 2.0.
