You are right.

In postfix/options.mk:

.if empty(PKG_OPTIONS:Mbdb)
PKG_OPTIONS+=   bdb             # "hash" map type is mandatory
.endif
.if !empty(PKG_OPTIONS:Mbdb)
USE_DB185=      no
.  include "../../mk/bdb.buildlink3.mk"
CCARGS+=        -DHAS_DB
AUXLIBS+=       ${BUILDLINK_LDFLAGS.${BDB_TYPE}} ${BDB_LIBS}
.endif

bdb is always aded to PKG_OPTIONS and it cause includes of
"../../mk/bdb.buildlink3.mk" and it seems to results use of db4.
(I don't know further...)
