The tablespace_map file is a temporary file containling a list of tablespace OID to tablespace file system path mappings.
tablespace_map is present from PostgreSQL 9.5.
用法
If this file is present in a server's data directory, it will be read on server start and the requisite tablespace symlinks (re)created; the file will be renamed to tablespace_map.old.
A tablespace_map is returned by pg_stop_backup() (PostgreSQL 15 and later: pg_backup_stop()).
