Bug reference: 5514
Logged by: Marcos Castedo
Email address: marcos.cast...@anachronics.com
PostgreSQL version: 8.4.4
Operating system: GNU/Linux
Description: no relation entry for relid X
Details:
Hi,
I'm getting an error in some kind of SQL expression (subquery referencing a
tuple from parent expression).
This error raise in 8.4.x version of postgres, but previous version (8.3.x)
execute the expression correctly.
Examples:
CREATE TABLE table_a
(
id integer primary key
);
CREATE VIEW view_a as select * FROM table_a;
SELECT (SELECT view_a) FROM view_a;
PostgreSQL 8.3.9 (works fine):
postgres=# SELECT (SELECT view_a) FROM view_a;
?column?
----------
(0 rows)
postgres=# INSERT INTO table_a VALUES (1);
postgres=# SELECT (SELECT view_a.*) FROM view_a;
?column?
----------
1
postgres=# SELECT (SELECT (view_a.*)::text) FROM view_a;
?column?
----------
(1)
(1 row)
PostgreSQL 8.4.4 (ERROR: no relation entry for relid x):
postgres=# SELECT (SELECT view_a) FROM view_a;
ERROR: no relation entry for relid 1
postgres=# INSERT INTO table_a VALUES (1);
postgres=# SELECT (SELECT (view_a.*)::text) FROM view_a;
ERROR: no relation entry for relid 1
postgres=# SELECT (SELECT view_a.*) FROM view_a;
?column?
----------
1
postgres=# SELECT (SELECT (a.*)::text) FROM view_a a;
ERROR: no relation entry for relid 1
Best regards
