Hi Chris or anyone who can help
When I try this just below, it complains about foo , saying “ERROR: schema

Thank you very much, I will try option 2 because option 1 will give me FK
constrains. These two databases are not exactly similar, but few tables on each
of these Databases needs to be exactly the same, in this case db1 is the
reliable one, hence that’s why I need to update db2 with what it’s in db1.

Hi all
Synchronizing a table that is in two different databases(e.g db1 and db2).
Please help me with this. I need to dump a table as INSERTS from db1 (postgres

Re: [GENERAL] Synchronizing a table that is in two different databases : Need to dump a table as inserts from db1 and change the insert statements into UPDATE statements
Hi Chris or anyone who can help
When I try this just below, it complains about foo (new table created in
db2) , saying *ERROR: schema foo does not exist*. I got stuck on this error
for a while now but still trying to see why but still no luck so far. If
you have something please help
begin;
update foo
set br_desc = bar.br_desc
, br_active = bar.br_active
(rest of columns)
where foo.br_cde = bar.br_cde;

Thank you very much, I will try option 2 because option 1 will give me FK
constrains. These two databases are not exactly similar, but few tables on
each of these Databases needs to be exactly the same, in this case db1 is
the reliable one, hence that's why I need to update db2 with what it's in
db1.

(For clarity, I'm going to call the table in question "foo".)
Option 1: If you just want to do a full copy of db1.foo to db2.foo, then
do that. Dump foo from db1, truncate foo in db2 and load db2.foo from the
dump. But you might not be able to do that (foreign keys and such). In
that case..
Option 2: Dump the table from db1, then load it into a table with a
different name ("bar") in db2. Then you can do this:
begin;
update foo
set br_desc = bar.br_desc
, br_active = bar.br_active
(rest of columns)
where foo.br_cde = bar.br_cde;
insert into foo (br_cde, br_desc, br_active, ...)
select br_cde, br_desc, br_active,
from bar
where not exists
( select *
from foo
where foo.br_cde = bar.br_cde);
commit;
