external_file extension v1.1 released

Grenoble - December 27, 2022

## PostgreSQL external_file extension

Allow access to "external files" from PostgreSQL server file systems.

This extension adds the same functionalities given by the Oracle's BFILE data
type that stores unstructured binary data in flat files outside the database.
A BFILE column stores a file locator that points to an external file containing
the data: (DIRECTORY, FILENAME). Here the data type is called EFILE.

The extension access to external files using secure call to the server side
lo_* functions and not by directly reading/writing to files.

external_file v1.1 has been released, this is a maintenance release to fix
issues reported by users since previous version.

- Add the efilename() function as equivalent to the Oracle BFILENAME() function.
- Improve Makefile and detect minimum version of PostgreSQL requirement.
- Fix make install error about file README.external_file.
