gbt_var_bin_union() failed to do the right thing when the existing range needed to be widened at both ends rather than just one end. This could result in an invalid index in which keys that are present would not be found by searches, because the searches would not think they need to descend to the relevant leaf pages. This error affected all the varlena datatypes supported by btree_gist (text, bytea, bit, numeric). Per investigation of a trouble report from Tomas Vondra. (There is also an issue in gbt_var_penalty(), but that should only result in inefficiency not wrong answers. I'm committing this separately so that we have a git state in which it can be tested that bad penalty results don't produce invalid indexes.) Back-patch to all supported branches. |

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.
