I also almost missed your mail. I was monitoring just the conversation
(gmail) that I sent you mail in, but since you changed the subject, it
almost was lost in the other traffic!!!

Maybe you want to post the this reply to the group. I'm now messing around

CC'ing the list

Looks like you almost got it right, just missing one step.

You mean the the link (Table Setup) on the homepage? Yeah, I did not notice
it, and expected it to work automatically!!!

2) Setup the tables you want to replicate.

For the tables created by the script I sent you earlier, (one int
primary-key, one normal int, columns), the entries are red; I did try the
databases individually, still didn't turn green. One thing though, when I
selected the databases individually, the background turned white, which,
according to comments on that page, means the rep-server was not able to
determine the status of this table.

I stopped the replication server from the control-panel and then fired the
following to create no-primary-key (identical) tables:

psql.exe -p 6543 test -c "create table test1( a int )"
psql.exe -p 5432 test -c "create table test1( a int )"
psql.exe -p 4321 test -c "create table test1( a int )"

And then again went to the 'Table Setup' page and now the new table (test1)
does show-up there, but it is also painted red!!!

Can you tell what is the problem here? Or can you give us a setup, tables
and some data, which can prove that it actually works!

3) START server.... you got that one.

One more thing Johnny, I asked for sources, others (Jonah) are also asking
for the same. I am sure the community won't show any interest in it if they
don't have the sources. So please consider sending the sources too; and as I
mentioned earlier, you can stick some liberal (preferably BSD) license in
the sources.

Best regards,
