Description: Wrong data type returned after CAST in FROM
Details:
Hello,
I noticed a strange nuance. When I do a regular select on data that I CAST
as a CHAR(), the data I am returned is of type character() as I would
expect. For example:
SELECT
CAST('abcd' AS CHAR(4)) AS data
This returns 'abcd' where the type is character(4).
However, if I do the cast in the FROM portion of the query such as this:
SELECT
data
FROM
CAST('abcd' AS CHAR(4)) AS data
then I am returned 'abcd' and the type is bpchar.
I did not have this issue when I was using Postgres 8.4. I upgraded last
week, and that's when I noticed the issue in a couple database functions I
had written.
