Description: VACUUM ANALYZE bug
Details:
Before I run the VACUUM ANALYZE command all query that use JOIN command
return the error: ERROR invalid typeLen: 0.
However the data of tables are unbroken.
Example:
create table departaments
( dp-id int,
name varchar(30),
primary key(dp-id) );
create table requests
( rq-id int,
dp-id int references departaments(dp-id),
description varchar(30),
primary key(dp-id) );
insert into departaments values (1,'Informatica');
insert into departaments values (2,'Recurcos Humanos');
insert into departaments values (3,'Compras');
insert into departaments values (4,'Marketing');
insert into departaments values (5,'Diretoria');
insert into departaments values (6,'Ensino');
insert into requests values (1,1,'nothing');
insert into requests values (2,1,'nothing');
insert into requests values (3,2,'nothing');
insert into requests values (4,3'nothing');
insert into requests values (5,4,'nothing');
insert into requests values (6,4'nothing');
select rq-id,name from requests left join departaments on requests.dp-id =
departaments.dp.id;
this result in:
rq-id | name
1 | Informatica
2 | Informatica
3 | Recursos Humanos
4 | Compras
5 | Marketing
6 | Marketing
now execute VACUUM ANALYZE.... the query dont work...
