Replicating lots of record

[FC]

Hello,

when replicating two Postegresql 8.4 databases, i have some problems when the two machines generate reports (during night-time) and produce about 7000/9000 rows each one.

Queued records for replicating in "rr_pending_changes" table grow up and i have to stop replication, sync databases and restart again.

How can i solve this problem, is someone had it?

Thank you!!

Regards,
Francesco
