For obscure reasons, some buildfarm members are now generating complaints about plpgsql_call_handler's "retval" variable possibly being used uninitialized. It seems no less safe than it was before that commit, but these complaints are (mostly?) new. I trust that initializing the variable where it's declared will be enough to shut that up. I also notice that some compilers are warning about setjmp clobber of the same variable, which is maybe a bit more defensible. Mark it volatile to silence that. Also, rearrange the logic to give procedure_resowner a single point of initialization, in hopes of silencing some setjmp-clobber warnings about that. (Marking it volatile would serve too, but its sibling variables are depending on single assignment, so let's stick with that method.)

PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download/ See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions.
