Fix hard coded formatting strings for 64 bit numbers (#1831) 
Postgres provides OS agnosting formatting macros for
formatting 64 bit numbers. Replaced %ld %lu with
INT64_FORMAT and UINT64_FORMAT respectively.

Also found some incorrect usages of formatting
flags and fixed them.

Onder Kalaci a273711500 The common attribute equivalance class always includes the input relations 
We added the ability to filter out the planner restriction information
for specific parts of the query. This might lead to situations where
the common restriction includes some other relations that we're searching
for. The reason is that while filtering for join restrictions, we add the
restriction as soon as we find the relation.

With this commit we make sure that the common attribute
equivalance class always includes the input relations.

Onder Kalaci 05fb0dd020 Add infrastructure for filtering restriction contexts based on the input query 
In subquery pushdown, we first ensure that each relation is joined with at least
on another relation on the partition keys. That's fine given that the decision
is binary: pushdown the query at all or not.

With recursive planning, we'd want to check whether any specific part
of the query can be pushded down or not. Thus, we need the ability to
understand which part(s) of the subquery is safe to pushdown. This commit
adds the infrastructure for doing that.

Onder Kalaci 26d9b58e9e Make sure that ExtractRangeTableRelationWalker never misses RTE_RELATION 2017-11-28 09:27:34 +02:00
Onder Kalaci 32def06ebd Split assigning RTE identities and partitioning related query modifications 
Note that we used to iterate over the RTEs once for performance reasons.
However, keeping an extra copy of original query seems more costly and
hard to maintain/explain.

Onder Kalaci 48f96bf3e5 Enable non equi joins in subquery pushdown 
Subquery pushdown planning is based on relation restriction
equivalnce. This brings us the opportuneatly to allow any
other joins as long as there is an already equi join between
the distributed tables.

We already allow that for joins with reference tables and
this commit allows that for joins among distributed tables.

With this commit, we allow pushing down subqueries with only
reference tables where GROUP BY or DISTINCT clause or Window
functions include only columns from reference tables.

Andres Freund d063658d6d Protect some initializations from being called during backend startup. 
On EXEC_BACKEND builds these functions shouldn't be called at every
backend start.

Brian Cloutier d267e0f9fa EXEC_BACKEND: don't put pointers to shared hashes into shared memory 
Store pointers to shared hashes in process-local variables. Previously
pointers to shared hashes were put into shared memory. This causes
problems on EXEC_BACKEND because everybody calls execve and receives a
brand new address space; the shared hash will be in a different place
for every backend. (normally we call fork, which gives you a copy of the
address space, so these pointers remain constant)
