The sto_using_cursor and sto_using_select tests were coded to exercise every permutation of their test steps, but AFAICS there is no value in exercising more than one. This matters because each permutation costs about six seconds, thanks to the "pg_sleep(6)". Perhaps we could reduce that, but the useless permutations seem worth getting rid of in any case. (Note that sto_using_hash_index got it right already.) While here, clean up some other sloppiness such as an unused table. This doesn't make too much difference in interactive testing, since the wasted time is typically masked by parallelization with other tests. However, the buildfarm runs this as a serial step, which means we can expect to shave ~40 seconds from every buildfarm run. That makes it worth back-patching.

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.
