As gist__int_ops stands in intarray, it is possible to store GiST entries for leaf pages that can cause corruptions when decompressed. Leaf nodes are stored as decompressed all the time by the compression method, and the decompression method should map with that, retrieving the contents of the page without doing any decompression. However, the code authorized the insertion of leaf page data with a higher number of array items than what can be supported, generating a NOTICE message to inform about this matter (199 for a 8k page, for reference). When calling the decompression method, a decompression would be attempted on this leaf node item but the contents should be retrieved as they are. The NOTICE message generated when dealing with the compression of a leaf page and too many elements in the input array for gist__int_ops has been introduced by |

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 "make all" and "make 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.
