Hello hackers,
I am researching about 'origin' in PostgreSQL, mainly it used in logical
decoding to filter transaction from non-local source.. I notice that the
'origin' is stored in commit_ts so that I think we are possible to get 'origin'
of a transaction from commit_ts.
But I can not fond any code to get 'origin' from commit_ts, just like it is
producing data which nobody cares about. Can I know what's the purpose
of the 'origin' in commit_ts? Do you think we should add some support
to the careless data?
For example, I add a function to get 'origin' from commit_ts:
=======================================
postgres=# select pg_xact_commit_origin('490');
pg_xact_commit_origin
-----------------------
test_origin
(1 row)
postgres=# select pg_xact_commit_origin('491');
pg_xact_commit_origin
-----------------------
test_origin1
(1 row)
postgres=#
=======================================
