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
The PostgreSQL contrib tree
---------------------------
This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly
because they address a limited audience or are too experimental to be
part of the main source tree. This does not preclude their
usefulness.
User documentation for each module appears in the main SGML
documentation.
When building from the source distribution, these modules are not
built automatically, unless you build the "world" target. You can
also build and install them all by running "gmake all" and "gmake
install" in this directory; or to build and install just one selected
module, do the same in that module's subdirectory.
Some directories supply new user-defined functions, operators, or
types. To make use of one of these modules, after you have installed
the code you need to register the new SQL objects in the database
system by executing a CREATE EXTENSION command. In a fresh database,
you can simply do
CREATE EXTENSION module_name;
See the PostgreSQL documentation for more information about this
procedure.
