villagesql-pgjwt

Packages the upstream vsql-pgjwt extension (signing, verifying and
decoding JWTs in SQL (pgjwt port)) as a separate snap that plugs into the
villagesql snap through the content interface:

sudo snap install villagesql-pgjwt
sudo snap connect villagesql:extensions villagesql-pgjwt:extensions
sudo snap restart villagesql
sudo villagesql.mysql -uroot -e "INSTALL EXTENSION vsqlpgjwt;"
sudo villagesql.mysql -uroot \

 -e "SELECT vsqlpgjwt.jwt_sign('{\"sub\":\"u\"}', 's', 'HS256');"
