Q1Domain Verified

In the context of developing PostgreSQL extensions using the provided course material, what is the primary mechanism for defining custom data types that can be indexed and manipulated within SQL queries?

Defining a SQL-based type using `CREATE TYPE` and then writing C functions for its input/output and binary representation.

Creating a new C function that returns a custom OID and registering it with `pg_type`.

Utilizing the `pg_attribute` catalog to define new type attributes and associating them with a pre-existing base type.

Implementing a custom C struct and registering its `typrelid` in `pg_class` for storage.

Q2Domain Verified

When developing a PostgreSQL extension that requires persistent storage for its custom data structures, what is the recommended approach for managing this data within the database, as detailed in the course?

Serializing the custom data structure into a `bytea` column and handling serialization/deserialization within C functions.

Defining a composite type using `CREATE TYPE` and storing instances of this type in a table with columns corresponding to the type's fields.

Leveraging external file system storage and accessing it via foreign data wrappers (FDWs).

Creating a new system catalog table using `CREATE TABLE` within the extension's control file and managing its schema directly.

Q3Domain Verified

A PostgreSQL extension needs to perform complex, stateful operations that are triggered by specific events within the database. What mechanism, as covered in the course, is most suitable for implementing and managing these event-driven, stateful operations?

Creating a series of scheduled `cron` jobs that query the database for changes and perform actions.

Implementing a custom `TRIGGER` function in C that maintains its state in global C variables.

Developing a custom background worker process that polls the transaction log for relevant events.

Utilizing PostgreSQL's built-in event trigger system (`EVENT_TRIGGER`) and registering custom functions to execute on defined events.
