Thanks for quick response, Keith.

Can you explain your point more deeply, why its a bad idea to do backup/restore of pg_attribute?

Hi, Gurus!!!!

Maybe someone knows what is the best way to shrink pg_attribute  in size? 
Maybe backup and restore of this table will sanitize "dead" records in it?
Or only full vacuum can help in this situation?

Thanks!

VACUUM FULL would be the way to go if bloat is the issue you're trying to fix. Trying to backup up & restore a single system catalog would not be recommended.
