Design problems were discovered in the handling of composite types and record types that would cause some relevant versions not to be recorded. Misgivings were also expressed about the use of the pg_depend catalog for this purpose. We're out of time for this release so we'll revert and try again. Commits reverted:1bf946bd: Doc: Document known problem with Windows collation versions.cf002008: Remove no-longer-relevant test case.ef387bed: Fix bogus collation-version-recording logic.0fb0a050: Hide internal error for pg_collation_actual_version(<bad OID>).ff942057: Suppress "warning: variable 'collcollate' set but not used".d50e3b1f: Fix assertion in collation version lookup.f24b1569: Rethink extraction of collation dependencies.257836a7: Track collation versions for indexes.cd6f479e: Add pg_depend.refobjversion.7d1297df: Remove pg_collation.collversion.

|
|
* pg_depend.h
|
|
* definition of the "dependency" system catalog (pg_depend)
|
|
*
|
|
* pg_depend has no preloaded contents, so there is no pg_depend.dat
|
|
* file; system-defined dependencies are loaded into it during a late stage
|
|
* of the initdb process.
|
|
*
|
|
* NOTE: we do not represent all possible dependency pairs in pg_depend;
|
|
* for example, there's not much value in creating an explicit dependency
|
|
* from an attribute to its relation. Usually we make a dependency for
|
|
* cases where the relationship is conditional rather than essential
|
|
* (for example, not all triggers are dependent on constraints, but all
|
|
* attributes are dependent on relations) or where the dependency is not
|
|
* convenient to find from the contents of other catalogs.
