I tested morning, sadly still something wrong...The problem is focus on one scenario, replicated mostly whole row deletes. It seems should not be relevant to the operation, but I can't find more relevant changes. We have already reset the compress context to fix the issue in the last months, it resolved most problems and seems more stable than before. But we have one circumstance, the replication always stuck. The senerio is as follows. There is two-way replications between cluster A and cluster B(both using wal group), A without WAL compression, B with WAL compression, write operations only on A. Now there are many whole row deletes on A, the replication of A->B is OK, the replication of B->A is always stucks, and the stuck is not rare, it is very easy to happen. I can not reproduce this problem locally until now, maybe it's not relevant to the uncompress progress, maybe something wrong when compress and the WAL is corrupt. I used WALPrettyPrinter to read these WALs, the printer always stopped at the same position for one WAL, and no exceptions output, but the end read position of the printer is in the middle of the WAL. -- This is an automated message from the Apache Git Service.
