Platform Heroku PG version 13

I have a very busy database and it is reaching near transaction wrap around.

At this point I really want to do the vacuum manually. My question is that if I do manual vacuuming of individual tables then I can see that the txid restores to its minimum value. But the global txid is not changed.

Is the individual vacuuming of tables enough ? Do I still have to do vacuum database ?

CodePudding user response：

Yes, a manual VACUUM of individual tables will do the trick.

Look at the relfrozenxid and relminmxid columns in the pg_class entries for that database. Find the oldest ones. One or more of these should be equal to datfrozenxid and datminmxid in pg_database. If you VACUUM those tables, the values for the database should advance.
