Hi all, Our current development database server is running a bit low on diskspace, so I dropped an old but rather large database with the intention of claiming back some space. However, the space remains claimed. This server was upgraded from PG10 to PG11 using pg_upgrade's --link option. I see this after having dropped the (300+GB) database: -bash-4.2$ du -d 1 -h 4.0K ./.cache 0 ./.config 4.0K ./9.6 376G ./10 72G ./11 447G . The files of that database apparently still exist within the ./10 directory: -bash-4.2$ du -d 1 -h ./10/data/ 4.1G ./10/data/pg_wal 816K ./10/data/global 0 ./10/data/pg_commit_ts 0 ./10/data/pg_dynshmem 8.0K ./10/data/pg_notify 0 ./10/data/pg_serial 0 ./10/data/pg_snapshots 208K ./10/data/pg_subtrans 0 ./10/data/pg_twophase 16K ./10/data/pg_multixact 372G ./10/data/base 0 ./10/data/pg_replslot 0 ./10/data/pg_tblspc 3.5M ./10/data/pg_stat 0 ./10/data/pg_stat_tmp 4.0K ./10/data/pg_logical 96K ./10/data/log 688K ./10/data/pg_xact 376G ./10/data/ How do I reclaim that space?
