[Bucardo-general] duplicate key value violates unique constraint "bucardo_sequences_tablename"

[Jonathan Brinkman]

Thanks so much. I'll try your SQL now.

Goodness I did paste the wrong syncs there.
These are the correct Master-to-2-slaves syncs that I will need to modify to
use the DBGroup as targetdb:
bucardo_ctl add sync cmsfgcc_pushdelta_main_to_gate1
source=cmsfgcc_main_to_gate targetdb=cmsfgcc_gate1 type=pushdelta 
bucardo_ctl add sync cmsfgcc_pushdelta_main_to_gate2
source=cmsfgcc_main_to_gate targetdb=cmsfgcc_gate2 type=pushdelta 

Thanks again

I didn't use bucardo_ctl (as I said) I did it in the DB...

psql -U bucardo bucardo will get you in there...

Then something like this shoudl work:

BEGIN;
INSERT INTO dbgroup (name, cdate) VALUES ('mydbseqsyncgrp', NOW()); INSERT
INTO dbmap (db, dbgroup, priority, cdate) VALUES ('cmsfgcc_gate1',
'mydbseqsyncgrp', 1, NOW()),('cmsfgcc_gate2', 'mydbseqsyncgrp', 1, NOW());
COMMIT;

Then add your sync with:

bucardo_ctl add sync cmsfgcc_pushdelta_gates_to_main source=cmsfgcc_main
targetdb=mydbseqsyncgrp type=pushdelta



... However, just re-reading your setup (I only quickly skimmed it at
first)... have you checked it's right...?

bucardo_ctl add sync cmsfgcc_pushdelta_gate2_to_main
source=cmsfgcc_gate2_to_main targetdb=cmsfgcc_main type=pushdelta
bucardo_ctl add sync cmsfgcc_pushdelta_gate1_to_main
source=cmsfgcc_gate1_to_main targetdb=cmsfgcc_main type=pushdelta


Both your targetdbs are the same... that doesn't look right ... perhaps you
meant to add them the other way around where the source is cmsfgcc_main and
the targets are to be gate1 and gate2...?
