That's not going to work. I want the row, I just don't want the values that are null.

Hi All!
I'm using the postgres json functions to generate json for values in a
table.
Something like this:

SELECT row_to_json(a_table) FROM a_table

But my data has lots of null values and that results in json attributes
like this:

"colname":null

I want to exclude those values from the json and only include non-null
values.
Any idea how to best go about this?

WHERE colname IS NOT NULL ?
