We have recently installed slony and tsrted replication on one of our test machines. When we start inserting data in to the replicated database, the replication is taking properly. Over a period of time the lag increases between the two database.
Looking further we found that, sl_log_1 and sl_log2 are not getting truncated. Following are the versions which we are using. Slony has been installed for the first time
Postgres version: 8.3.5 slony version: 2.0.0
Can someone let me know what we should be looking at?
Following is the error which we get:
