Hi all,

there was a question on #postgresql (irc-channel) from CyberDuck without
an answer. A little example:

test=*# select generate_series(1,5), generate_series(6,10) order by 1;
 generate_series | generate_series
-----------------+-----------------
               1 |               6
               2 |               7
               3 |               8
               4 |               9
               5 |              10
(5 rows)

test=*# select generate_series(1,5), generate_series(7,10) order by 1;
 generate_series | generate_series
-----------------+-----------------
               1 |               7
               1 |               8
               1 |               9
               1 |              10
               2 |               8
               2 |               9
               2 |              10
               2 |               7
               3 |               9
               3 |              10
               3 |               7
               3 |               8
               4 |              10
               4 |               7
               4 |               8
               4 |               9
               5 |               7
               5 |               8
               5 |               9
               5 |              10
(20 rows)

Why returns the first select 5 rows (i think, this is okay) and the 2nd
20 rows?

Version is a 8.1 on Debian.
