A :cache_file plugin option has been added to the pg_auto_constraint_validations plugin. This option specifies a file to use to cache the metadata the plugin uses, so the plugin does not need to run 5 queries per model at startup to load the metadata. This can dramatically improve startup time when using the plugin with a large number of models.
To create the metadata file, load the plugin into
Sequel::Model(or whatever class you are using as the base class for your model classes) with the :cache_file option, and after loading all of the subclasses of that class, run:
As when using the schema_caching and index_caching extensions, it is up to the user to ensure that the cached metadata matches the current database schema.
Sequeldoes no checking of this, as checking would take more time, and the point of this plugin is to improve startup performance.
A static_cache_cache plugin has been added. This plugin allows for caching rows for models using the static_cache plugin. This prevents the need to issue a query at model creation time to get the rows. This plugin should be loaded into
Sequel::Model(or whatever class you are using as the base class for your model classes) before loading the models using the static_cache plugin. To create the metadata file, after all subclasses of that class have been loaded, run:
:unique_deferrable and :primary_key_deferrable column options are now supported on PostgreSQL 9+ and Oracle. This allows you to created deferrable unique and primary key column constraints. You could already create deferrable table constraints using the :deferrable option to the primary_key and unique methods.
A :generated_always_as column option is now supported on PostgreSQL 12+, for creating generated columns.
A Database#skip_logging? private method has been added. This is designed for use in extensions, to force log timing even when no loggers are configured.
All database array types are converted to Ruby arrays in the jdbc adapter. Previously, this was only done in the jdbc/postgresql subadapter.
