Prevent maintanince deamon crashes due to dead processes
...
If after the distributed deadlock detection decides to cancel
a backend, the backend has been terminated/killed/cancelled
externally, we might be accessing to a NULL pointer. This commit
prevents that case by ignoring the current distributed deadlock.

Add alias for target in multi-row INSERTs

Add alias for target in multi-row INSERTs
...
This is necessary for multi-row INSERTs for the same reasons we use it
in e.g. UPSERTs: if the range table list has more than one entry, then
PostgreSQL's deparse logic requires that vars be prefixed by the name
of their corresponding range table entry. This of course doesn't affect
single-row INSERTs, but since multi-row INSERTs have a VALUE RTE, they
were affected.
The piece of ruleutils which builds range table names wasn't modified
to handle shard extension; instead UPSERT/INSERT INTO ... SELECT added
an alias to the RTE. When present, this alias is favored. Doing the
same in the multi-row INSERT case fixes RETURNING for such commands.

Add Savepoint Support ( #1539 )
...
This change adds support for SAVEPOINT, ROLLBACK TO SAVEPOINT, and RELEASE SAVEPOINT.
When transaction connections are not established yet, savepoints are kept in a stack and sent to the worker when the connection is later established. After establishing connections, savepoint commands are sent as they arrive.
This change fixes #1493 .

Switch to Postgres REL_STABLE_10 branch
...
PostgreSQL master branch is now stamped with 11devel and we should
only use master branch if we want to test against PostgreSQL 11. For
PostgreSQL 9.6 tests we should use REL9_6_STABLE and for PostgreSQL 10
we should use REL_10_STABLE. v0.6.4 tag in our tools repo addresses
this problem.
Apart from that we may want to add PostgreSQL 11 to our test matrix soon.
v0.6.4 handles that too. We just need add PostgreSQL 11 to our test matrix
and stop erroring out if we are compiling Citus against PostgreSQL 11.
