I can not find "amcostestimate" in hash.h or anywhere, or am I
missing something?

Search for hashcostestimate here:

http://git.postgresql.org/gitweb?p=postgresql.git;a=blob;f=src/backend/utils/adt/selfuncs.c

To find that, I ran this query:

select * from pg_am;

That showed me that the name for the hash implementation of that
function was hashcostestimate. Then I ran this in my bash shell, at
the root of the source tree:

find -name '*.h' -or -name '*.c' \
| egrep -v '^\./src/test/.+/tmp_check/' \
| xargs egrep -n '\bhashcostestimate\b'
