============================================================================
POSTGRESQL BUG REPORT TEMPLATE
============================================================================

Your name : Sergey E. Levov
Your email address : serg@informika.ru

System Configuration
---------------------
Architecture (example: Intel Pentium) : Intel Pentium Pro

Operating System (example: Linux 2.0.26 ELF) : FreeBSD 2.2.5

PostgreSQL version (example: PostgreSQL-6.3.2) : PostgreSQL-6.3.2

Compiler used (example: gcc 2.7.2) : gcc 2.7.2.1

Please enter a FULL description of your problem:
------------------------------------------------
When I declare cursor for select statement without "ORDER BY" clause
( select * from <tablename> ), and then attempt to fetch record after
last record in table, or even just give "fetch all" command,
all the following "fetch" commands, regardless direction, will return
an empty result sets.
If "SELECT" statement has "ORDER BY" clause, all works well.

Please describe a way to repeat the problem. Please try to provide a
concise reproducible example, if at all possible:
----------------------------------------------------------------------
Try the following sequence of SQL operators:

begin
declare mycurs cursor for select * from pg_user
fetch all in mycurs - OK
fetch backward all in mycurs - fails
move backward all in mycurs
fetch all in mycurs - fails
close mycurs

declare mycurs cursor for select * from pg_user order by usename
fetch all in mycurs - OK
fetch backward all in mycurs - OK
move backward all in mycurs
fetch all in mycurs - OK
