OK, in theory we could do the following, no?
Use our PITR logs to restore a tertiary system to the point when we
were having the problem (we have a pretty wide 2 or 3 hour window to
hit), then query the pg_locks table on that system?
If so, is it possible to only restore a subset of the DB to that point
- in particular just this table?
The problem is that our DB is pretty massive and this could take an
extremely long time.
