Hi everyone,

I created a simple scenario to understand the handling of 
TOASTs<https://www.postgresql.org/docs/current/storage-toast.html>: There is an 
empty database with a single table and record. The single record gets updated 
multiple times with 10MB (bytea column). I can see that the table/toasttable 
size is growing (500MB).

Now I tried to find a way to get the DB size down again (it should be around 
10MB instead of 500MB). I don’t want to use VACUUM FULL due to the exclusive 
lock.

Is there any way to remove the dead tuples and free the pages?

Thanks in advance &
Best regards,
Manuel
