I would have thought these would be stored in memory. If the set got

It does not. Cursors are implicitly closed when a session is closed. A
backend crash or system restart closes all open sessions.

Edit the file with a text editor. If you know which files should be
excluded (like tags files), use diff --exclude=<pattern>.
