Hello all.
Recently, when working with the hstore and json formats, I came across the fact that PostgreSQL has a cast of hstore to json, but there is no reverse cast. I thought it might make it more difficult to work with these formats. And I decided to make a cast json in the hstore. I used the built-in jsonb structure to create it and may have introduced methods to increase efficiency by 25% than converting the form jsonb->text->hstore. Which of course is a good fact. I also wrote regression tests to check the performance. I think this extension will improve the work with jsonb and hstore in PostgreSQL.
If you've read this far, thank you for your interest, and I hope you enjoy this extension!
