- Notes
-
-
- When using collations provided by the ICU library, the ICU-specific version
- of the collator is recorded in the system catalog when the collation object
- is created. When the collation is used, the current version is
- checked against the recorded version, and a warning is issued when there is
- a mismatch, for example:
-
-WARNING: collation "xx-x-icu" has version mismatch
-DETAIL: The collation in the database was created using version 1.2.3.4, but the operating system provides version 2.3.4.5.
-HINT: Rebuild all objects affected by this collation and run ALTER COLLATION pg_catalog."xx-x-icu" REFRESH VERSION, or build PostgreSQL with the right library version.
-
- A change in collation definitions can lead to corrupt indexes and other
- problems because the database system relies on stored objects having a
- certain sort order. Generally, this should be avoided, but it can happen
- in legitimate circumstances, such as when
- using pg_upgrade to upgrade to server binaries linked
- with a newer version of ICU. When this happens, all objects depending on
- the collation should be rebuilt, for example,
- using REINDEX. When that is done, the collation version
- can be refreshed using the command ALTER COLLATION ... REFRESH
- VERSION. This will update the system catalog to record the
- current collator version and will make the warning go away. Note that this
- does not actually check whether all affected objects have been rebuilt
- correctly.
-
-
- When using collations provided by libc and
- PostgreSQL was built with the GNU C library, the
- C library's version is used as a collation version. Since collation
- definitions typically change only with GNU C library releases, this provides
- some defense against corruption, but it is not completely reliable.
-
-
- Currently, there is no version tracking for the database default collation.
-
-
-
- The following query can be used to identify all collations in the current
- database that need to be refreshed and the objects that depend on them:
- pg_collation_actual_version(c.oid)
- ORDER BY 1, 2;
-]]>
