PostgreSQL triggers - QGIS freezes when saving layer edits

Using PostgreSQL triggers saving layer edits gets slower and slower every time when saving a layer edit. The problem occurs after a few up to a few dozen saved layer edits. Finally QGIS freezes completely.

I've tried the posted triggers in the folowing link:

Seems it is not a PostgSQL trigger issue. On Windows 7 QGIS 2.12.3 gets slower every time when saving a layer edit. Can someone edit the title?

Layer is a PostgreSQL/PostGIS table.

Do I understand correctly it still happens without any trigger defined ?
What kind of edits do you make ?
Can you provide a step-by-step guide on how to reproduce ?

I'm unchecking "causes crash or corruption" as I understand there's no corruption and no crash (but a freeze, which may be prevented by closing qgis after some edits, and re-opening, right ?)

Meanwhile I suppose it's neither a trigger nor a PostGIS issue. Most of the time I'm just adding new features. QGIS gets slower every time saving layer edits. After restarting QGIS everything is fine again until saving a few layer edits. I will provide a step by step guide within the next few days.

Try disabling all plugins. This behaviour is typical of badly behaved plugins.

I've uninstalled all plugins and now everything seems to work. Many thanks!
