Remove the contrib/start-scripts/osx scripts since they are no longer recommended (use contrib/start-scripts/macos instead) (Tom Lane), Remove the chkpass extension (Peter Eisentraut). However, if a fast upgrade fails, you must restore the database from the backup. The directory structure under the specified directories on the primary and standbys must match. As side note: are you aware that before Postgres 10, the version numbering was a bit different? Fix failure of parallel B-tree index scans when the index condition is unsatisfiable (James Hunter), Ensure that data is detoasted before being inserted into a BRIN index (Tomas Vondra), Index entries are not supposed to contain out-of-line TOAST pointers, but BRIN didn't get that memo. Always run the pg_upgrade binary of the new server, not the old one. How to Upgrade PostgreSQL 11 to PostgreSQL 12 with Zero Downtime Allow the creation of partitions based on hashing a key column (Amul Sul), Support indexes on partitioned tables (lvaro Herrera, Amit Langote). Allow bitmap scans to perform index-only scans when possible (Alexander Kuzmenkov), Update the free space map during VACUUM (Claudio Freire). Regular upgrades can take a considerable amount of time, depending on the size of the database and the speed of the storage system. Add the ability to define PL/pgSQL composite-type variables as not null, constant, or with initial values (Tom Lane), Allow PL/pgSQL to handle changes to composite types (e.g., record, row) that happen between the first and later function executions in the same session (Tom Lane). I started with 9.1. (They are usually small.) If it is selected but not supported, the pg_upgrade run will error. E.20.3.1. Do not load the schema definitions, e.g., CREATE EXTENSION pgcrypto, because these will be duplicated from the old cluster. Connect and share knowledge within a single location that is structured and easy to search. Add Vietnamese letter handling to the unaccent extension (Dang Minh Huong, Michael Paquier), Enhance amcheck to check that each heap tuple has an index entry (Peter Geoghegan), Have adminpack use the new default file system access roles (Stephen Frost). This could lead to errors like missing chunk number 0 for toast value NNN. Speed up construction of query results (Andres Freund), Improve speed of access to system caches (Andres Freund), Add a generational memory allocator which is optimized for serial allocation/deallocation (Tomas Vondra). An index on a partitioned table is not a physical index across the whole partitioned table, but rather a template for automatically creating similar indexes on each partition of the table. (The community will attempt to avoid such situations.). It facilitates building covering indexes that optimize specific types of queries. In PostgreSQL 10: $ pg_dumpall -s > schema.sql. In some situations the path name for the current directory might be too long to be a valid socket name. The backup will only be taken for the schema, since the information will be replicated in the initial transfer. Is there a standard approach to rolling out database schema changes? This option causes pg_upgrade to return without waiting, which is faster, but means that a subsequent operating system crash can leave the data directory corrupt. Previously, only superusers could call adminpack functions; now role permissions are checked. The PostgreSQL Project thanks Nick Cleaton for reporting this problem. PostgreSQL: Documentation: 15: Appendix E. Release Notes The release notes do not contain changes that affect only a few users or changes that are internal and therefore not user-visible. The script files will connect to each database that needs post-upgrade processing. This improves the robustness of the algorithm for both uniform and non-uniform distributions. Reduce var = var to var IS NOT NULL where equivalent (Tom Lane). The PostgreSQL Global Development Group has released an update to all supported versions of PostgreSQL, including 14.3, 13.7, 12.11, 11.16, and 10.21. Verify that the Latest checkpoint location values match in all clusters. We can insert some test records in our PostgreSQL 10 and validate that we have them in our PostgreSQL 11: At this point, we have everything ready to point our application to our PostgreSQL 11. This new TLS LDAP method for encrypted LDAP is enabled with ldapscheme=ldaps or ldapurl=ldaps://. Previously, tab completion queries could fail against older servers. If you use link mode, the upgrade will be much faster (no file copying) and use less disk space, but you will not be able to access your old cluster once you start the new cluster after the upgrade.
