More references to hash: in default config, postfix-hash package messages

Just some quick observations after an update to 3.9 with lmdb.

The default configuration contains hash: as examples in main.cf, maybe patching those to lmdb: is acceptable here (I know, this deviates from the upstream configuration from postfix, but creates less confusion - there is also already a postfix-3.5.8-main_defaults.patch patch file, maybe this one can be adapted?).

If you call newaliases for instance (and you happen to have hash: in main.cf) you get:

postalias: warning: unsupported dictionary type: hash. Is the postfix-hash package installed? postalias: fatal: unsupported map type: hash

As far as I can tell, there is no postfix-hash package being built, PKGBUILD contains:

pkgname=( postfix postfix-{cdb,ldap,lmdb,mongodb,mysql,pcre,pgsql,sqlite} )

The file to patch here is:

postfix-3.9.0/src/global/dynamicmaps.c:

if ((dp = (DYMAP_INFO *) htable_find(dymap_info, dict_type)) == 0) { msg_warn("unsupported dictionary type: %s. " "Is the postfix-%s package installed?", dict_type, dict_type); return (0);

Patching this I would say is rather cosmetic and is more something which should be done in Postfix itself when one disabled certain map type.. :-)
