Hi,
I guess its simply because String fields in postgres can not be larger than 1 GB, long type could represent length values far beyond this limit surpassing postgres limits.

I don’t know why the first method was not implement,because the column can not store the ‘value’ whoes lengthis the ‘length’? Or other reason? Thank you.
