Hello,

I won't be able to work on foreign keys pointing to partitioned tables
for the next commitfest, so if somebody is interested in seeing it
supported, I applaud they working on it and I offer a bit of time to
discuss it, if they're so inclined:

CREATE TABLE pktab (a int PRIMARY KEY) PARTITION BY RANGE (a);
... create some partitions ...

CREATE TABLE fktab (a int REFERENCES pktab);


Thanks,
