Hi, it's not clear to me when tuple data (max 1000 bytes total) get compressed on disk and when not. I tried with pg_column_size to find the tuple's size but I get ambiguous results.
What is the table definition? Maybe this will help?: https://www.postgresql.org/docs/9.5/static/storage-toast.html
It seems to work but sometimes the tuples seem compressed and sometime not. I tried both with constant data and random bytes. Thanks Pupillo
