Thanks for updating the patch set.
Here are some comments:
===
For 0002 patch.
1. The typo atop the function EventTriggerTableInitWrite.
```
+/*
+ * Fire table_init_rewrite triggers.
+ */
+void
+EventTriggerTableInitWrite(Node *real_create, ObjectAddress address)
```
s/table_init_rewrite/table_init_write
~~~
2. The new process for "SCT_CreateTableAs" in the function
pg_event_trigger_ddl_commands.
With the event trigger created in
test_ddl_deparse_regress/sql/test_ddl_deparse.sql, when creating the table that
already exists with `CreateTableAs` command, an error is raised like below:
```
postgres=# CREATE TABLE IF NOT EXISTS as_select1 AS SELECT * FROM pg_class
WHERE relkind = 'r';
postgres=# CREATE TABLE IF NOT EXISTS as_select1 AS SELECT * FROM pg_class
WHERE relkind = 'r';
NOTICE: relation "as_select1" already exists, skipping
ERROR: unrecognized object class: 0
CONTEXT: PL/pgSQL function test_ddl_deparse() line 6 at FOR over SELECT rows
```
It seems that we could check cmd->d.ctas.real_create in the function
pg_event_trigger_ddl_commands and return NULL in this case.
===
For 0004 patch.
3. The command tags that are not supported for deparsing in the tests.
```
FOR r IN SELECT * FROM pg_event_trigger_ddl_commands()
-- Some TABLE commands generate sequence-related commands, also
deparse them.
WHERE command_tag in ('ALTER FOREIGN TABLE', 'ALTER TABLE',
'CREATE FOREIGN
TABLE', 'CREATE TABLE',
'CREATE TABLE AS',
'DROP FOREIGN TABLE',
'DROP TABLE', 'ALTER
SEQUENCE',
'CREATE SEQUENCE',
'DROP SEQUENCE')
```
Since foreign table is not supported yet in the current patch set, it seems that
we need to remove "FOREIGN TABLE" related command tag. If so, I think the
following three files need to be modified:
- test_ddl_deparse_regress/sql/test_ddl_deparse.sql
- test_ddl_deparse_regress/t/001_compare_dumped_results.pl
- test_ddl_deparse_regress/t/002_regress_tests.pl
~~~
4. The different test items between meson and Makefile.
It seems that we should keep the same SQL files and the same order of SQL files
in test_ddl_deparse_regress/meson.build and test_ddl_deparse_regress/Makefile.
===
For 0004 && 0008 patches.
5. The test cases in the test file
test_ddl_deparse_regress/t/001_compare_dumped_results.pl.
```
# load test cases from the regression tests
-my @regress_tests = split /\s+/, $ENV{REGRESS};
+#my @regress_tests = split /\s+/, $ENV{REGRESS};
+my @regress_tests = ("create_type", "create_schema", "create_rule",
"create_index");
```
I think @regress_tests should include all SQL files, instead of just four. BTW,
the old way (using `split /\s+/, $ENV{REGRESS}`) doesn't work in meson.
