Re: RDS and postgres extension approval - Mailing list pgsql-admin

Hi-- maybe more an RDS question, but does anyone know how extensions go about being approved for use in PG on RDS? For example, we'd like to make use of plpython3u but you get the old "Extension "plpython3u" is not supported by Amazon RDS" error..

You should try PLPerl. That extension is supported by RDS:

https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_PostgreSQL.html#PostgreSQL.Concepts.General.FeatureSupport.Extensions.12x

Your code will look prettier, thanks to perltidy. You will also get the whole of CPAN in your toolkit. Above all, you will not have to use COBOL-like tabulation. Whatever you can do in Python, you can also do in Perl. And, as always, use strict.

#!/usr/bin/perl -w                                      # camel code
use strict;

Note that in the language that enforces indentation rules, the code above would not be possible.
