In log I see that links was created. But pg_upgrade copies all databases. In destination data folder I see files, not links, and if no free space on disk for copy all data, error appear while upgrade.
Unfortunately, I have no idea what encoding you used, so I can't read the file. I tried some windows encoding but no luck, can you send the file in utf8 or mention which encoding you're using? Could you also specify the full pg_upgrade command line you're using?
Hard links are not easy to distinguish from regular files in Windows. If you identify a file path from a relation in a user database, like so:
test=# select pg_relation_filepath(c.relname::text) from pg_class c test-# join pg_namespace n on n.oid = c.relnamespace test-# where n.nspname not in ('information_schema', 'pg_catalog') and c.relkind = 'r' limit 1; pg_relation_filepath ---------------------- base/16384/16385 (1 row)
And then check the links of this file:
C:\> fsutil hardlink list %PGDATA%/base/16384/16385
You should see two locations. Can you please confirm this?
