No.  That looks like it covers it.  I must have missed that when it came in.  
Thanks for pointing it out.

Thomas Leuxner's patch from #815659 msg. #45 adds a new binary package
postfix-lmdb including the relevant .so, in the fashion of postfix-cdb,
postfix-mysql, etc.  If that's not what you mean by “a separate binary”,
please explain and I'll be happy to give a hand on that.

Just a lack of time.

We do want to make this a separate binary, so it's a bit more complicated than 
the patch in the bug.  If someone could provide a patch for that, it would 
surely help.

Anything blocking on this?  It would be great to have LMDB support in
Stretch :-)

Thanks for maintaining Postfix in Debian!

I'd like to second this; I'm also able to create and query LMDB maps
after applying the patch.  Just one remark though: although harmless,
the conditional ‘delmap’ in the postinst script doesn't seem useful
since Postfix < 2.3.3-3 isn't compiled with LMDB support.

Furthermore, the debian/postfix-lmdb.* are identical to their -cdb
counterparts, thus postfix-lmdb and postfix-cdb have the same lintian
warnings.  In particular, the prerm scripts other than the one for -doc
trigger ‘maintainer-script-empty’ (they only seem to contain comments
and boilerplate code), hence should probably be removed.  IMHO this
doesn't belong to this patch though.

In that case, we'll want to put this into a separate binary package.  This is 
on our radar to do, but if you can put together a complete patch, that will 
get it done that much sooner.

It misses some magic to be performed on dynamicmaps.cf which I fixed manually. 
Also LMDB is included in the base package this way. Please consider including 
LMDB support going forward.

Bug#815659: postfix: Build Postfix 3.x with LMDB Support

[Thomas Leuxner]

Source: postfix
Version: 3.0.4-1
Severity: normal

Dear Maintainer,

What is the proper way of including LMDB support in Postfix 3.x? The rules seem 
to have changed in the new series. Postfix 2.11 has been previously built 
successful in the same environment:

[ debian/rules for 3.x]:

CCARGS += -DDEBIAN -DHAS_PCRE -DHAS_LDAP -DUSE_LDAP_SASL \
-DHAS_SQLITE -DMYORIGIN_FROM_FILE \
$(shell getconf LFS_CFLAGS) \
-DHAS_CDB \
-DHAS_LMDB -I/usr/include \
-DHAS_MYSQL -I/usr/include/mysql \
-DHAS_PGSQL -I`pg_config --includedir` \
-DHAS_SQLITE -I/usr/include \
-DHAS_SSL -I/usr/include/openssl \
-DUSE_SASL_AUTH -I/usr/include/sasl \
-DUSE_CYRUS_SASL \
-DUSE_TLS

AUXLIBS += -lssl -lcrypto -lsasl2 -lpthread
AUXLIBS_LMDB="-L/usr/lib -llmdb -lpthread"

Above recipe fails to include LMDB support using "dpkg-buildpackage".
