velioglu	0a56ed910b	Change error message of queries with distributed and local table Citus can handle INSERT INTO ... SELECT queries if the query inserts into local table by reading data from distributed table. The opposite way is not correct. With this commit we warn the user if the latter option is used.	2017-09-22 13:46:19 -07:00

Marco Slot	2f8ac82660	Execute INSERT..SELECT via coordinator if it cannot be pushed down Add a second implementation of INSERT INTO distributed_table SELECT ... that is used if the query cannot be pushed down. The basic idea is to execute the SELECT query separately and pass the results into the distributed table using a CopyDestReceiver, which is also used for COPY and create_distributed_table. When planning the SELECT, we go through planner hooks again, which means the SELECT can also be a distributed query. EXPLAIN is supported, but EXPLAIN ANALYZE is not because preventing double execution was a lot more complicated in this case.	2017-06-22 15:46:30 +02:00
