> We can support SPLIT_PART function for Postgres:
> {{ split_part}} ( _{{string}}_ {{{}text{}}}, _{{delimiter}}_ {{{}text{}}},
> _{{n}}_ {{integer}} ) → {{text}}
> Splits _{{string}}_ at occurrences of _{{delimiter}}_ and returns the
> {_}{{n}}{_}'th field (counting from one), or when _{{n}}_ is negative,
> returns the |{_}{{n}}{_}|'th-from-last field.
> {noformat}
> split_part('abc#def#ghi', '#', 2) # returns 'def'
> split_part('abc,def,ghi,jkl', ',', -2) # returns 'ghi'
> {noformat}
