Assuming I have a table in PostgreSQL, how can I find the exact byte size used by the system in order to save a specific row of my table?
For example, assume I have a table with a
VARCHAR(1000000)
field and some rows contain really big strings for this field while others really small. How can I check the byte size of a row in this case? (including the byte size even in the case TOAST is being used).
