Description:

I love Postgres !! And also its documentation !!

While reading through data types, it occurred to me that most ( if not every
) other data types has a chart on the top saying how many bytes it
occuies.
Like all numerical, date or char data types.

For enum it would be nice to have that info as well.
I am assuming it is variable ? May be 1 or 2 bytes for the definition and
the rest depending on the enum values ? 

A clarification would be nice !

Thanks

Second to last sentence on the page.

Storage only measures the size of a single value on a data row.

Thanks David. I overlooked that at the bottom. I guess it would still be nice to mention the storage at the top like other data types.
