Hackers,
For my [explanation extension](http://pgxn.org/extension/explanation) I wanted to put together a list of node types,
sinceI'm always having to figure them out to decide which nodes I'm interested in. Reading
src/backend/commands/explain.cI assembled this list:
+ Aggregate + Append + Bitmap Heap Scan + Bitmap Index Scan + BitmapAnd + BitmapOr + CTE Scan +
ForeignScan + Function Scan + Group + Hash + Hash Join + Index Scan + Limit + LockRows + Materialize
+Merge Append + Merge Join + ModifyTable + Nested Loop + Recursive Union + Result + Seq Scan + SetOp +
Sort + Subquery Scan + Tid Scan + Unique + Values Scan + WindowAgg + WorkTable Scan
Is that accurate? I was looking at how `sname` was set, but maybe it can be set other ways?
Should a list like this be added to the EXPLAIN docs?
Thanks,
David
