Re: BUG #15653: pg_detoast_datum_packed problem

Hi,

/* SQL function: bvarchar(varchar) returns bytea */

PG_FUNCTION_INFO_V1(pg_bvarchar);
Datum pg_bvarchar(PG_FUNCTION_ARGS) {
   VarChar *arg = PG_GETARG_VARCHAR_PP(0);
     unsigned    len;
     bytea       *res;
     len = VARSIZE( arg ) - VARHDRSZ;
     res = (text *)palloc( len + VARHDRSZ );
     SET_VARSIZE( res, len + VARHDRSZ );
     memcpy( VARDATA( res ), VARDATA( arg ), len);
     PG_RETURN_BYTEA_P(res);
}
