When we decide that we don't want to track execution time of a specific planner or ProcessUtility call, we still have to increment the nesting depth, or we'll make the wrong determination of whether we are at top level when considering nested statements. (PREPARE and EXECUTE are exceptions, for reasons explained in the code.) Counting planner nesting depth separately from executor nesting depth was a mistake: it causes us to make the wrong determination of whether we are at top level when considering nested statements that get executed during planning (as a result of constant-folding of functions, for example). Merge those counters into one. In passing, get rid of the PGSS_HANDLED_UTILITY macro in favor of explicitly listing statement types. It seems somewhat coincidental that PREPARE and EXECUTE are handled alike in each of the places where that was used: the reasoning tends to be different for each one. Thus, the macro seems as likely to encourage future bugs as prevent them, since it's quite unclear whether any future statement type that might need special-casing here would also need the same choices at each spot. Sergei Kornilov, Julien Rouhaud, and Tom Lane, per bug #17552 from Maxim Boguk. This is pretty clearly a bug fix, but it's also a behavioral change that might surprise somebody, so no back-patch.

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.
