> > We can support split_part function for postgresq:
> > 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.
> > ```
> > split_part('abc~@def@ghi', '@~', 2) → def
> >
> > split_part('abc,def,ghi,jkl', ',', -2) → ghi
> > ```
>
> select split_part('abc~@def@ghi', '@~', 2); return nothing in PG. There is
a typographical error here.
