Back in 2010 I submitted a small feature to allow the creation of minidumps when backends crashed; see commit dcb09b595f88a3bca6097a6acc17bf2ec935d55f .
At the time Windows lacked useful support for postmortem debugging and crash-dump management in the operating system its self, especially for applications running as services. That has since improved considerably.
The feature was also included in 9.4
Ahem. 9.1. This is what I get for multi-tasking between writing this and packaging an extension for 9.4.
In which version(s) of Windows was this improvement added? I think that's really the part that matters here, not necessarily which version of PostgreSQL.
