[HACKERS] Typo in doc/src/sgml/catalogs.sgml

Hi,

I found a minor typo at
https://www.postgresql.org/docs/9.6/static/catalog-pg-am.html.

pg_catalog.pg_am. amhandler is of type "oid" according to the
documentation, but it's actually of type "regproc" in reality.

Compare with e.g. pg_aggregate where the columns of type "regproc" is
both "regproc" in the documentation and in reality.

To fix:

diff --git a/doc/src/sgml/catalogs.sgml b/doc/src/sgml/catalogs.sgml
index 29738b0..93deda4 100644
