This tidies up some questionable coding which made use of DatumGetPointer() for Datums being passed into functions where the parameter is expected to be a cstring. We saw no compiler warnings with the old code as the Pointer type used in DatumGetPointer() happens to be a char * rather than a void *. However, that's no excuse and we should be using the correct macro for the job. Here we also make use of OutputFunctionCall() rather than using FunctionCall1() directly to call the type's output function. OutputFunctionCall() is the standard way to do this. It casts the returned value to a cstring for us. In passing get rid of a duplicate call to strlen(). Most compilers will likely optimize away the 2nd call, but there may be some that won't. In any case, this just aligns the code to some other nearby code that already does this. Discussion: https://postgr.es/m/CAApHDvq1D=ehZ8hey8Hz67N+_Zth0GHO5wiVCfv1YcGPMXJq0A@mail.gmail.com |

PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. 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. The latest version of this software may be obtained at https://www.postgresql.org/download/. For more information look at our web site located at https://www.postgresql.org/.
