The documentation says nothing about it … so no I have no clue. Personally, I tend to use that function in R more than I do in PostgreSQL.

Hi,
Query is working properly when column_name::integer is used. I wonder Why is it required when column type is already set to int4. Any idea?

What do you get with the following two type castings:
SELECT coalesce(column_name::integer, 255); ?

“integer” might actually be “smallint” if you’re only going to 255.

There is table with int4 column. When select query is executed as "select coalesce(column_name, 255), query is failing with below error.
"COALESCE types text and integer cannot be mached".
Any idea?
Thank You!!
