I have a comment on something like that to: Why - when creating a view
using explicit * on select - postgresql reads all the fields in the query
and especify them one by one on the view definition? Developers always have
to check every view after changing a table definition to be certain it does
not need to be recreated.
That's a bug or a feature?

Assunto: [HACKERS] bug? Drop column and SQL functions
Someone showed me this simple example:
regression=# CREATE TABLE test (a TEXT, b TEXT);
CREATE TABLE
regression=# INSERT INTO test VALUES ('foo', 'bar');
INSERT 17145 1
regression=# CREATE FUNCTION foo() RETURNS SETOF test as 'SELECT * FROM
test' LANGUAGE sql;
CREATE FUNCTION
regression=# SELECT * FROM foo();
a | b
-----+-----
foo | bar
(1 registro)
regression=# ALTER TABLE test DROP COLUMN a;
ALTER TABLE
regression=# SELECT * FROM foo();
ERROR: query-specified return row and actual function return row do not
match
(note that I didn't "specify a return record" -- SETOF test should only
consider non-dropped columns ...)
