After delete worked and the a foreach execute update seems to work best.
Below is a satisfactory test set.
-- create test table
CREATE TABLE test1 (
a int,
b int,
c int);
-- create resort function
CREATE OR REPLACE FUNCTION resort_test1() RETURNS TRIGGER AS '
DECLARE
eachrow RECORD;

Hi,
Can pg transform
SELECT * FROM (
SELECT 'foo' AS class, id FROM foo
UNION ALL
SELECT 'bar' AS class, id FROM bar
) AS a WHERE class = 'foo'
into
SELECT 'foo' AS class, * FROM foo?
The subselect is a view here, that's why I don't just use the second
query.

I have a table that looks like this:CREATE TABLE my_table ( pkey serial PRIMARY KEY, fkey int NOT NULL REFERENCES my_other_table( pkey ), uid int NOT NULL REFERENCES user( pkey ), seq1 int, seq2 int);Basically, for each fkey that exists in my_table, there is a sequence represented by

[ experiments... ] Yes, if you spell it like this:
regression=# explain SELECT *
I'm not sure if this is the best thing to do in all occasions, but I have
found a great speed increase using unions over group by.
select fkey, uid, seq2 from mytable where seq2 > 2 and seq1 = ( select
min(seq1) from mytable);
union
select fkey, uid, seq2 from mytable where seq2 > 2 and seq1 =
Hi,
it seems to me that the following should work but it fails:
CREATE VIEW co AS SELECT LOCALTIMESTAMP::TIMESTAMP AS ov WHERE FALSE;
CREATE TABLE link (ov TIMESTAMP);
CREATE OR REPLACE VIEW co AS SELECT ov FROM link;

That's strange. I explicitly specified ::TIMESTAMP on both the view and
the table. Is that not unambiguous?
