hi.
similar to NUMERIC_DEBUG. I made the following adjustments.
if unnecessary, removing this part seems also fine, in GDB, you can
print it out directly.
/* ----------
* Uncomment the following to get a dump of a array's ndim, dim, lBound.
* ----------
#define ARRAYDEBUG
*/
#ifdef ARRAYDEBUG
{
StringInfoData buf;
initStringInfo(&buf);
appendStringInfo(&buf, "array_in- ndim %d, dim info(", ndim);
for (int i = 0; i < MAXDIM; i++)
appendStringInfo(&buf, " %d", dim[i]);
appendStringInfo(&buf, "); lBound info(");
for (int i = 0; i < MAXDIM; i++)
appendStringInfo(&buf, " %d", lBound[i]);
appendStringInfo(&buf, ") for %s", string);
elog(DEBUG1, "%s", buf.data);
pfree(buf.data);
}
#endif
other than this, no other changes.
