Description:        Debugging doesn't work in version 8.3.12 on windows.
Details:

Debugging doesn't work in version 8.3.12. Debugging window doesn't open at
all when using "Debugging > Debug" menu command from pgAdmin. And when using
"Debugging > Set breakpoint" and then calling function - function just
executes without stopping at breakpoint. The same happens in versions 8.3.11
and 8.3.10. The last version where debugging worked was 8.3.9.
