I had a brief look at DB2's row_number function which seems to be pretty
useful.
What it does is:
test=# SELECT row_number(), relname FROM pg_class LIMIT 3;
row_number |relname
+
1 | pg_description
2 | pg_group
3 | pg_proc
(3 rows)
Here is how I doi it when I need to...
BEGIN;
CREATE TEMP SEQUENCE row_num;
SELECT next_val('row_num'), relname FROM pg_class LIMIT 3;
ROLLBACK;
You could also do this with a Set Returning Fucntion so that it returns the
nextval in a simular way

question is: How do I find out when a query starts? Inside a table
function I can call SRF_IS_FIRSTCALL() to see when it is called first.
Is there an easy way to check that inside an ordinary C function
returning just one
