pg_str 0.2.1

Adds str functions to Postgresql via an extension.
# Postgresql String Extension

A better way of handling string manipulation and transformations in Postgresql.

Function api and behavior is inspired by those available in the Laravel web framework: https://laravel.com/docs/8.x/helpers#strings-method-list

## Installation
```
git clone git@github.com:abumni/pg_str
cd pg_str
cargo pgx package # run cargo install pgx first
sudo make install # adjust Makefile if using different version of postgresql than 13.
```
This puts the binaries and sql into the right folder location. Next you need to create the extension in postgresql:

```
psql
> create extension pg_str; # installs functions in a schema named 'str'
> select str.markdown('# Hello '
|| str.snake('pg str')
|| '- ~~using programming language for str manipulations~~ 
- **do it all in postgresql** ');
```
