TEXT SEARCH DICTIONARY objects depend on TEXT SEARCH TEMPLATE objects.
Since we do not yet support distributed TS TEMPLATE objects, we skip
dependency checks for text search templates, similar to what we do for
roles.
The user is expected to manually create the TEXT SEARCH TEMPLATE objects
before a) adding new nodes, b) creating TEXT SEARCH DICTIONARY objects.
DESCRIPTION: Implement TEXT SEARCH CONFIGURATION propagation
The change adds support to Citus for propagating TEXT SEARCH CONFIGURATION objects. TSConfig objects cannot always be created in one create statement, and instead require a create statement followed by many alter statements to get turned into the object they should represent.
To support this we add functionality to the worker to create or replace objects based on a list of statements. When the lists of the local object and the remote object correspond 1:1 we skip the creation of the object and simply mark it distributed. This is especially important for TSConfig objects as initdb pre-populates databases with a dozen configurations (for many different languages).
When the user creates a new TSConfig based on the copy of an existing configuration there is no direct link to the object copied from. Since there is no link we can't simply rely on propagating the dependencies to the worker and send a qualified
