Thanks for the response Tim. I have not been destroying my layers. This has not been an issue when running the plugin with 2.0.
This was the first thing I thought about in the version running against master so I added the following code to close the postgis layers as it once I am finished with them: QgsMapLayerRegistry.instance().removeMapLayer(layer_id) This has not made it difference. It still hangs at the same place and I still get the warning that there is already too many clients when trying to connect to PostGIS with DB Manager or pgAdmin. Shall I open a bug?

Recently this script has developed an issue. It uses QGIS-dev so it could be related to some of the changes in master recently as it works fine with QGIS 2.0. It makes about 42 PDFs then it stops. It is not actually crashing as such, as you can see it running in task manager. It stays running using between 0 and 2% processor, and fluctuates a little with memory use (around 108840kB). But it does not produce any more PDFs. It is like it is stuck. >From the log file that my script creates, I know that it is hanging with this >line of code: vlayer = QgsVectorLayer(uri.uri(), layerName, "postgres") If I try and connect to the database using DB Manager in QGIS or pgAdmin III while the script is still running, I get an error saying there is already too many clients already. If I kill the process in windows task manager, I am then able to connect to the database using DB manager. Has anyone any suggestions as to what is wrong here? Is this a bug? I updated QGIS dev this morning using the OSGeo4W installer (its revision is eb9ce3a). If you are creating postgis layers in a loop, are you making sure to destroy them again nicely in your loop? Anyway if it used to work before maybe there was a regression somewhere....
