Add timeout for add-table operation to avoid possible locking issues.
sql/pgq: fix retry-queue vs. newgrants
deb: include data_maintainer3 in package
londiste.handlers.dispatch: fixed "ignore events aiming at obsolete partitions" bug
debian/changelog: updated
Merge branch 'hotfix/3.1.5.3'
Merge branch 'master' of skype-git:/git/dba/skytools-3
Merge remote-tracking branch 'gamato/master'

Conflicts:
	debian/changelog
deb: support Postgres 9.3, 9.4
sql/pgq: tag pgq.batch_id_seq as dumpable (extension)

That case was broken in old 9.1 releases, fixed since 9.1.7.

The sequence will be owned by extension and without tagging
it will not be dumped in data dump.
