Hi Norbi,
If the number of tenant schemas is reasonably static, you could write a
plpgsql function to create a set of UNION ALL views with one view for each
table in all tenant schemas. You could re-run the function each time a
tenant schema is added. Having the set of views would allow you to que
Could you use an interval data type? For example:
b2bcreditonline=# create table interval_example (i interval);
CREATE TABLE
b2bcreditonline=# insert into interval_example values
('26:15:32'::interval);
INSERT 0 1
b2bcreditonline=# select * from interval_example;

Hi,
I'm in the process of migrating a cluster from 15.3 to 16.2. We have a
'zero downtime' requirement so I'm using logical replication to create the
new cluster and then perform the switch in the application.
I have a situation where all but one table have done their initial copy.

Maybe you could create a function that has a required parameter, so rather
than 'select * from huge_view where .." they do 'select * from
function(some_ssn) [where...]' ?
That function would then query the view using the supplied ssn.
Just a thought.

You need to prefix the rhs column(s) with 'excluded.'. For example:

I don't know why you think advisory locks are the solution. It seems
regular row locks would ensure you have exclusive access to the customer.

I agree with Michael. Another consideration is how the composite type is
