Undo logs for unlogged relations are\nremoved in the same circumstances that unlogged relations are.  The tablespace\nused by each session is controlled by the GUC undo_tablespaces.  The columns\ntablespace and persistence show this in the pg_stat_undo_logs view.\nTablespaces containing undo logs can be dropped and that automatically drops\nthe undo logs, but this is only allowed if no backend is attached and\ncurrently in a transaction.\n\nWarning: Some interlocking problems may remain, and recovery is still being\nworked on.  Recovery and concurrent backup are still being worked on.  There\nare known bugs in the checkpointing protocol that are being worked on.\nTemporary relations appear to work superficially, but are not actually\ntemporary yet (they use shared buffers and their data is stored on disk\npermanently).\n\nThomas Munro","distinct":true,"url":"https://api.github.com/repos/EnterpriseDB/zheap/commits/e8de9c6ecb2771c1cf248bf28bf5957a8e6e0f39"}]}
