Agreed.
Barring any further comments/objections, I'll go ahead and prepare a
patch to add this to core.
So it will return a text representation or an Oid?
Looks like regtype displays as an integer. So how about pg_regtypeof()
and pg_typeof()?
PG_FUNCTION_INFO_V1(pg_regtypeof);
Datum
pg_regtypeof(PG_FUNCTION_ARGS)
{
PG_RETURN_OID(get_fn_expr_argtype(fcinfo->flinfo, 0));
}
PG_FUNCTION_INFO_V1(pg_typeof);
Datum
pg_typeof(PG_FUNCTION_ARGS)
{
Oid typeoid;
typeoid = get_fn_expr_argtype(fcinfo->flinfo, 0);
if (typeoid == InvalidOid) {
ereport(
ERROR, (
errcode(ERRCODE_FEATURE_NOT_SUPPORTED),
errmsg("could not determine data type of argument to
pg_typeof()")
)
);
}
PG_RETURN_DATUM(CStringGetDatum(format_type_be(typeoid)));
}
Best,
David
