Replace calls to unsafe functions like memcpy and sscanf

In answer to a security audit, we double check buffer sizes and avoid
known-dangerous operations such as sscanf.

Ensure to use initialized MaxBackends
...
Postgresql loads shared libraries before calculating MaxBackends.
However, Citus relies on MaxBackends being set. Thus, with this
commit we use the same steps to calculate MaxBackends while
Citus is being loaded (e.g., PG_Init is called).
Note that this is safe since all the elements that are used to
calculate MaxBackends are PGC_POSTMASTER gucs and a constant
value.

Make sure the explain output for partition wise join is stable
...
We disable bunch of planning options on the workers. This might be
risky if any concurrent test relies on EXPLAIN OUTPUT as well. Still,
we want to keep this test, so we should try to not parallelize this
test with such test.

INSERT...SELECT via coordinator with ON CONFLICT/RETURNING
2018-11-30 16:23:49 +03:00

Support INSERT...SELECT with ON CONFLICT or RETURNING via coordinator
...
Before this commit, Citus supported INSERT...SELECT queries with
ON CONFLICT or RETURNING clauses only for pushdownable ones, since
queries supported via coordinator were utilizing COPY infrastructure
of PG to send selected tuples to the target worker nodes.
After this PR, INSERT...SELECT queries with ON CONFLICT or RETURNING
clauses will be performed in two phases via coordinator. In the first
phase selected tuples will be saved to the intermediate table which
is colocated with target table of the INSERT...SELECT query. Note that,
a utility function to save results to the colocated intermediate result
also implemented as a part of this commit. In the second phase, INSERT..
SELECT query is directly run on the worker node using the intermediate
table as the source table.

Since there is no lock ordering among the query that is executed
and the select from the view, we prefer to add a timeout before

Refrain from having a strong opinion on maxGroupId.
...
When initializing a Citus formation automatically from an external piece of
software such as Citus-HA, the following process process may be used:
- decide on the groupId in the external software
- SELECT * FROM master_add_inactive_node('localhost', 9701, groupid => X)
When Citus checks for maxGroupId, it forbids other software to pick their
own group Ids to ues with the master_add_inactive_node() API.
This patch removes the extra testing around maxGroupId.
