Cool.

From documentation:

CREATE INDEX ... [ IF NOT EXISTS name | name ] ON ...

Maybe I'm just slow, but it took me a few minutes to understand what
this means. :)

I would add a human-language explanation to IF NOT EXISTS description: Index name is required when IF NOT EXISTS is
specified

You have resurrected this bit again, which now conflicts with git master...

- write_msg(NULL, "reading row-security enabled for table \"%s\"",
+ write_msg(NULL, "reading row-security enabled for table \"%s\"\n",

---- n->concurrent = $4;
+ n->if_not_exists = false; n->idxname = $5;

Minor stylistic thing: now that this is a constant, I would move it to
the end together with other constant assignments, and follow the
struct's field ordering (in both code paths):

n->isconstraint = false;
n->deferrable = false;
n->initdeferred = false;
n->if_not_exists = false;
