If the remote database's settings of these GUCs are different from ours, ambiguous datetime values may be read incorrectly. To fix, temporarily adopt the remote server's settings while we ingest a query result. This is not a complete fix, since it doesn't do anything about ambiguous values in commands sent to the remote server; but there seems little we can do about that end of it given dblink's entirely textual API for transmitted commands. Back-patch to 9.2. The hazard exists in all versions, but this patch would need more work to apply before 9.2. Given the lack of field complaints about this issue, it doesn't seem worth the effort at present. Daniel Farina and Tom Lane
