Thanks for the report. For some reason, I am not getting these errors
with my compiler
[ashutosh@ubuntu regress]gcc --version
gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3
Anyway, I have fixed it in the attached patch.
The patch is based on sources upto commit
commit 2a7f4f76434d82eb0d1b5f4f7051043e1dd3ee1a

and Amit Langote's set of patches posted on 15th Sept. 2016 [1]
There are few implementation details that need to be worked out like
1. adjust_partitionrel_attrs() calls adjust_appendrel_attrs() as many
times as the number of base relations in the join, possibly producing
a new expression tree in every call. It can be optimized to call
adjust_appendrel_attrs() only once. I will work on that if reviewers
agree that adjust_partitionrel_attrs() is needed and should be
optimized.
2. As mentioned in earlier mails, the paths parameterized by parent
partitioned table are translated to be parameterized by child
partitions. That code needs to support more kinds of paths. I will
work on that, if reviewers agree that the approach of translating
paths is acceptable.
3. Because of an issue with declarative partitioning patch [2]
multi-level partition table tests are failing in partition_join.sql.
Those were not failing with an earlier set of patches supporting
declarative partitions. Those will be fixed based on the discussion in
that thread.
4. More tests for foreign tables as partitions and for multi-level
partitioned tables.
5. The tests use unpartitioned tables for verifying results. Those
tables and corresponding SQL statements will be removed once the tests
are finalised.
