Hi,
w.r.t. 0001-Partial-aggregates-push-down-v03.patch
For partial_agg_ok(),
+ if (agg->aggdistinct || agg->aggvariadic || agg->aggkind !=
AGGKIND_NORMAL || agg->aggorder != NIL)
+ ok = false;
Since SearchSysCache1() is not called yet, you can return false directly.
+ if (aggform->aggpartialpushdownsafe != true)
The above can be written as:
if (!aggform->aggpartialpushdownsafe)
For build_conv_list():
+ Oid converter_oid = InvalidOid;
+
+ if (IsA(tlentry->expr, Aggref))
...
+ }
+ convlist = lappend_oid(convlist, converter_oid);
Do you intend to append InvalidOid to convlist (when tlentry->expr is
not Aggref) ?
Cheers
