When there is a Postgres archiver stuck because of filled pg_xlog and archive directories...
... and the pg_xlog directory had been filled with dozens of GBs of xlogs...
...it takes ages until the archive_command had moved all xlogs from the pg_xlog directory to the archive directory afterwards...
... and you get crazy if you have a 8GB archive directory while the pg_xlog directory had been pumped up to 100GB :(
Any idea on this one?
