What I'd like to do is use dblink to extract a few rows from a remote
database and manipulate these within a function in pl/pgsql. Something
like this:
CREATE OR REPLACE FUNCTION find() RETURNS INTEGER AS '
DECLARE
count INTEGER:
myrec RECORD;
BEGIN
FOR myrec IN SELECT * FROM DBLINK(''select x,y from mytab'') as

Is there a way to rollback a dblink transaction?
Say, I delete some data from the remote database, but I don't want this
to be visible untill the data is inserted in the current database. And
if the insertion of data in the current database throws an error, I want
to rollback the dblink transaction, which should restore data in its
original remote location.
Thanks.

Hello,
I've been experimenting with dblink recently, and have encountered some
limitations I'd like to discuss.
I've been trying to create views of remote tables, like so:
CREATE VIEW stuff AS
SELECT *
FROM dblink(' ... remote connection info ... ',
'SELECT id, title, title_idx FROM stuff')

Hello all!
I am rather stuck and am hoping someone can help. I am working on a
project where users need to be able to send one query which will hit
databases on multiple hosts (the database structures are the same) and
tie the data back together again.
After doing lots of reading it looks like dblink might be a great
solution for this. After trying to insert dblink.sql into the database,
I just get a series of errors:

Hello,
we want use dblink to connect several databases in a client/server environment. Connection from local users to the remote databases should be possible only for privileged users. We tried a solution with dblink, embedding this command in a view, like this:
create view inst as select * from dblink('host=pollux port=5432 dbname=cob_int user=his_int password=#integration#', .....
This solution is insecure, because login and password...

Hi list,
My boss would like to convert from MySQL to PostgreSQL, but there are a few
things that hold us back.
We'd like to have the databases in several physical servers, with referential
integrity between the tables. Reading from Oracle articles, their
referential integrity can be done using their dblink and triggers. What I'd
like to ask is whether contrib/dblink is stable? Seeing dblink in a contrib
directory does bring a doubt...

Hi, I wanted to copy a data from table1 in db1 to table2 in db2, which has the same structure, with the PosgreSQL dblink funtion.
The fields for both the tables are: id, first_name, last_name.
However, I would like to replace the id and first_name in table1 to: 3 and 'nil' to insert into table2.
INSERT INTO table2 SELECT * FROM dblink('dbname=db1', 'SELECT 3, nil, last_name FROM table1 WHERE id = 1000') AS t1(id integer, first_name...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
