Reset default theme per application

Some applications look ugly when using dark theme. So there is a way to reset theme per application, just change its launch command.
 For example to reset pgadmin theme:

Try from console:
env GTK2_RC_FILES= GTK_DATA_PREFIX= /usr/bin/pgadmin3

Launch shortcut:
Edit this file /usr/share/applications/pgadmin3.desktop
Change Exec= to env GTK2_RC_FILES= GTK_DATA_PREFIX= /usr/bin/pgadmin3
