This ameliorates problems with slow shutdown of replication workers.Īvoid crash after function syntax error in replication workers (Maxim Orlov, Anton Melnikov, Masahiko Sawada, Tom Lane) If decoding begins partway through a transaction that modifies system catalogs, the decoder may not recognize that, causing it to fail to treat that transaction as in-progress for catalog lookups.Īccept interrupts in more places during logical decoding (Amit Kapila, Masahiko Sawada) Prevent examining system catalogs with the wrong snapshot during logical decoding (Masahiko Sawada) These errors could lead to assertion failures in debug builds, and otherwise to memory leaks. This mistake is not known to have any negative consequences within core PostgreSQL, but it did cause issues for some extensions.įix bugs in logical decoding when replay starts from a point between the beginning of a transaction and the beginning of its subtransaction (Masahiko Sawada, Kuroda Hayato) When a PostgreSQL instance performing archive recovery (but not using standby mode) is promoted, and the last WAL segment that it attempted to read ended in a partial record, the instance would write an invalid WAL segment on the new timeline.įix mis-ordering of WAL operations in fast insert path for GIN indexes (Matthias van de Meent, Zhang Mingli) Prevent WAL corruption after a standby promotion (Dilip Kumar, Robert Haas) This oversight could lead to assertion failures or planner errors such as “ variable not found in subplan target list”. This typically manifested as failure of consistency checks in the executor but a crash or incorrect data updates are also possible.Īvoid flattening FROM-less subqueries when the outer query has grouping sets (Tom Lane) ) with an inherited or partitioned target table could result in failure if the child tables are sufficiently dissimilar. Repair rare failure of MULTIEXPR_SUBLINK subplans in inherited updates (Tom Lane) This avoids confusion between a view's ON SELECT rule and any other rules it may have. This oversight could lead to “ cache lookup failed for type” errors, or in older branches even to crashes.ĭisallow rules named _RETURN that are not ON SELECT (Tom Lane) Previously, a buggy operator class or corrupted index could indefinitely prevent completion of vacuuming of the index, eventually leading to transaction wraparound problems.įix handling of DEFAULT tokens that appear in a multi-row VALUES clause of an INSERT on an updatable view (Tom Lane) Rather than throwing an error, just log the issue and continue without deleting the empty page. Read more about minor version upgrades here.Fix VACUUM to press on if an attempted page deletion in a btree index fails to find the page's parent downlink (Peter Geoghegan) Crunchy Bridge clusters are automatically updated with new minor versions automatically in the course of other operations, such as plan or storage changes, failovers, and other maintenance. The community releases minor versions at least four times a year, and sometimes more often. Need to upgrade your Crunchy Bridge cluster? Read more about how to upgrade or get in touch for additional help. If a cluster is still running a Postgres version when Bridge availability ends, it will be automatically upgraded it to a newer version. To ensure the security and operability of a cluster, we must phase out Postgres versions before the community/PostgreSQL Global Development Group ends their support.
