Message-ID: <CAAMgDXkrDTZwo3v=vcGd0=axjEg9BV09LL=f2+n=DShFBmAV9Q@mail.gmail.com> (raw)
Hello All,
we have this set up :
Postgres 15.13 on RHEL 9.6
Logical Master also have 2 streaming replica
Logical Replica also have 1 streaming replica
We just do patch updates from 15.12 to 15.13, restart Logical Master and
then Logical Replica, and suddenly Logical replication stops working.
Streaming replication of both are fine.
The message on Logical Replica :
ERROR,08P01,"could not receive data from WAL stream: ERROR: invalid memory
alloc request size 1095736448",,,,,,,,,"","logical replication worker",,0
The message on Logical Master :
"START_REPLICATION", LOG,00000,"starting logical decoding for slot
""_subscription""","Streaming transactions committing after 33D45/373C2D98,
reading WAL from 33D44/EF3219B0.",,,,,"START_REPLICATION SLOT
""_subscription"" LOGICAL 33D45/373C2D98 (proto_version '3',
publication_names '""_publication""')",,,"_subscription","walsender",,0
"START_REPLICATION", ,LOG,00000,"logical decoding found consistent point at
33D44/EF3219B0","Logical decoding will begin using saved
snapshot.",,,,,"START_REPLICATION SLOT ""_subscription"" LOGICAL
33D45/373C2D98 (proto_version '3', publication_names
'""_publication""')",,,"_subscription","walsender",,0
Checking at error code 08P01 is protocol_violation.
Is there any idea on what causing this and how to resolve ?
