Does it equal to execute "CREATE ACCESS METHOD"?

Sorry, I open another mail list to ask this question.

When I add
"{ oid => '6015', oid_symbol => 'SPB_AM_OID',
descr => 'SPB index access method',
amname => 'spb', amhandler => 'spbhandler', amtype => 'i' },"
in pg_am.dat
and add
"{ oid => '388', descr => 'spb index access method handler',
proname => 'spbhandler', provolatile => 'v',
prorettype => 'index_am_handler', proargtypes => 'internal',
prosrc => 'spbhandler' }," in pg_proc.dat,

so when I use the make install && cd contrib;make install;
whether it equals to execute create access method?

by the way, I've added the spb codes in src/access/spb, so don't worry about the spbhandler.

And Sorry for the another mail "access method xxx does not exist", you suggest me add new
Am Index in contrib, But I need to modify gist to spb, so that's not my require. And I need to know
add those in pg_proc.dat and pg_am.dat, if it won't create access method for spb, what else I need to
do?

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.

thanks for your advice, I realize my problems, can you give me some materials like some study routine for pg-internal?
