Did you run initdb afterwards? What you describe here should
result in an updated postgres.bki file, but that isn't the
same as catalog entries in a live database.

To be very blunt, it doesn't sound to me that your skills with
Postgres are anywhere near up to the task of writing a new
index access method. You should start with some less-ambitious
project to gain some familiarity with the code base.
