That change table should have at lease few additional columns
* Operation (I/D/U)
* txid
* Commit_time_stamp
If you look at logical decoding, that's basically what you have, isn't
it? It won't go into a table, but you can consume it into one if you
want. Look at for example wal2json for examples of how to consume it
-- but the system is pluggable so you can build your own or use one of
the others available plugins.
Hello,
At my work, we basically did that, using wal2json, here:
https://github.com/peopledoc/connemara/blob/master/connemara_replication/src/connemara_replication.c
The code is quite simple, you could probably inspire yourself from that,
or even use it directly if your needs are basic and match was is
offered. The replication code was written to be as fast and simple as
possible.
