How it works...

When you issue a CREATE EXTENSION command, the database server looks for a file named EXTNAME.control in the SHAREDIR/extension directory. That file tells PostgreSQL some properties of the extension, including a description, some installation information, and the default version number of the extension (which is unrelated to the PostgreSQL version number). Then, a creation script is executed in a single transaction; thus, if it fails, the database is unchanged. The database server also notes in a catalog table the extension name and all the objects that belong to it.
