[HACKERS] clone varlena function

[Pavel Stehule]

Hello,

I am cleaning orafce module and I would to eliminate duplicit code
with core. Is in core similar macro or function?

text*
ora_clone_text(text *t)
{
        text *result;

        result = palloc(VARSIZE(t));
        SET_VARSIZE(result, VARSIZE(t));
        memcpy(VARDATA(result), VARDATA(t), VARSIZE(t) - VARHDRSZ);

        return result;
}

It can be used for any varlena datatype.

Thank you
Pavel Stehule
