I faced it, when I was trying to get values from database.
This issue throws error that could not open directory “pg_tblspc/<1234…x>”: No such file or directory
To solve this issue you first have to create dump of your database. Steps are ahead …
- psql -h localhost -p 6666 -U postgres -d <yourDBname>-f “E:/xyz/abc.p”
(It will create dump file of your database)
- Then delete your old database after dumping it.
(dump database <yourDBname>)
- Then again restore it from your dump file…
Or, Its better to use your backup file while restoring..
If problem is still there then we need to first restore that <abc.p/abc.sql> file on our local machine
- then again create (.p) file as dump file
- And restore your postgres by using this new dump file…
You will not come across this problem again……..
Another way:-
1) Backup data with pg_dump
pg_dump -i -h localhost -p 5432 -U postgres -F c -b -v -f
“/usr/local/backup/10.70.0.61.backup” old_db
To list all of the available options of pg_dump, please issue following command.
- Ø pg_dump -?
-p, –port=PORT database server port number
-i, –ignore-version proceed even when server version mismatches
-h, –host=HOSTNAME database server host or socket directory
-U, –username=NAME connect as specified database user
-W, –password force password prompt (should happen automatically)
-d, –dbname=NAME connect to database name
-v, –verbose verbose mode
-F, –format=c|t|p output file format (custom, tar, plain text)
-c, –clean clean (drop) schema prior to create
-b, –blobs include large objects in dump
-v, –verbose verbose mode
-f, –file=FILENAME output file name
2) Restore data with pg_restore
pg_restore -i -h localhost -p 5432 -U postgres -d old_db -v
“/usr/local/backup/10.70.0.61.backup”
