I'm guessing the reason is something like this: even though the "things"
returned by these two statements are the same logical entity (from a
mathematics/set theory standpoint):
pg_dev=# select * from unnest(array[1,2,3]);
unnest
1
2
3
(3 rows)
pg_dev=# select unnest(a
Possibly due to my lack of thorough SQL understanding. Perhaps there's a
better way of doing what I'm ultimately trying to accomplish, but still the
question remains - why does this work:
pg_dev=# select unnest(array[1,2,3]);
unnest
1
2
3
(3 rows)
But not this:
pg_dev

Hi,
I have a UDF (written in C) that returns SETOF RECORD of an anonymous
record type
(defined via OUT parameters). I'm trying to use array_agg() to transform
its output to
an array:
pg_dev=# SELECT array_agg((my_setof_record_returning_func()).col1);
