When building a list of relations for a parallel processing of a schema or a database (or just a single-entry list for the non-parallel case with the database name), the list is allocated and built on-the-fly for each database processed, leaking after one database-level reindex is done. This accumulates leaks when processing all databases, and could become a visible issue with thousands of relations. This is fixed by introducing a new routine in simple_list.c to free all the elements in a simple list made of strings or OIDs. The header of the list may be using a variable declaration or an allocated pointer, so we don't have a routine to free this part to keep the interface simple. Per report from coverity for an issue introduced by 5ab892c, and valgrind complains about the leak as well. The idea to introduce a new routine in simple_list.c is from Tom Lane.

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.
