------------------------------------------------
Dear list members,
We are developing an application that uses Postgresql as its dbms.
It seems we've found a bug in PostgreSQL handling of cursored queries.
I assume that it's legal to do 'fetch backward all in xxx' and then
'fetch 1 in xxx' afterwards. If it is not legal in Postgresql, the rest
of this mail is irrelevant. (I have been using Postgresql for quite a
long time now, and I experienced that you cannot 'fall off' of neither
ends of a query result by moving the cursor.)
Please describe a way to repeat the problem. Please try to provide a
concise reproducible example, if at all possible:
----------------------------------------------------------------------
So the bug appears when I execute the following steps:
1.
in psql shell: => create database test;
=> create user tester with password 'tester';
2.
in the os's shell: $ psql -d test -U tester -f ss3.sql
$ psql -d test -U tester
3.
in psql shell: => \i test5a.sql
=> fetch 1 in lionhart;
=> fetch -1 in lionhart;
=> fetch 1 in lionhart;
??? last fetch should return a row, but it doesn't seem like...
Attached files:
ss3.sql : The dumped content of my database
test5a.sql : The query we would use
If you know how this problem might be fixed, list the solution below:
