We want, say, 2 to be transformed as 2, not \\2 which is what the original coding produced. Perl's standard seems to be to add an RV wrapper only for hash and array SVs, so do it like that. This was missed originally because the test cases only checked what came out of a round trip back to SQL, and the strip-all-dereferences loop at the top of SV_to_JsonbValue hides the extra refs from view. As a better test, print the Perl value with Data::Dumper, like the hstore_plperlu tests do. While we can't do that in the plperl test, only plperlu, that should be good enough because this code is the same for both PLs. But also add a simplistic test for extra REFs, which we can do in both. That strip-all-dereferences behavior is now a bit dubious; it's unlike what happens for other Perl-to-SQL conversions. However, the best thing to do seems to be to leave it alone and make the other conversions act similarly. That will be done separately.

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/.
