@WritingConverter does not properly convert string to ltree in Postgres

[wodinga]

When creating a Writing converter to convert from string to to ltree, it runs, but it doesn't actually convert to ltree.

@WritingConverter
class LtreeWritingConverter : Converter < String, PGobject > {
    override fun confvert(source: String): PGobject {
        return PGObject().apply {
            type = "ltree"
            value = source
       }
    }
}

Workaround:

CREATE CAST (varchar AS ltree) WITH INOUT AS IMPLICIT;

This allows us to write strings as ltrees in the Postgres DB
