Thanks for the new patch set.
Here are some comments:
For v-80-0002* patch.
1. The comments atop the function deparse_IndexStmt.
+ * Verbose syntax
+ * CREATE %{unique}s INDEX %{concurrently}s %{if_not_exists}s %{name}I ON
+ * %{table}D USING %{index_am}s %{definition}s %{with}s %{tablespace}s
+ * %{where_clause}s %{nulls_not_distinct}s
+ */
+static ObjTree *
+deparse_IndexStmt(Oid objectId, Node *parsetree)
Since we added decoding for the [ONLY] option in this version, it seems that we
also need to add related comments, like this:
```
%{table}D USING %{index_am}s %{definition}s %{with}s %{tablespace}s
->
%{only}s %{table}D USING %{index_am}s %{definition}s %{with}s %{tablespace}s
```
===
For v-80-0003* patch.
2. In the function deparse_CreateTrigStmt.
I think we need to parse the [OR REPLACE] option for CREATE TRIGGER command.
And I think there are two similar missing in the functions
deparse_DefineStmt_Aggregate (option [OR REPLACE]) and
deparse_DefineStmt_Collation (option [IF NOT EXISTS]).
===
For v-80-0004* patch.
3. There are some whitespace errors:
Applying: Introduce the test_ddl_deparse_regress test module.
.git/rebase-apply/patch:163: new blank line at EOF.
+
.git/rebase-apply/patch:3020: new blank line at EOF.
+
.git/rebase-apply/patch:4114: new blank line at EOF.
+
warning: 3 lines add whitespace errors.
Hou zj and I will try to address these comments soon.
