Thanks for addressing my previous review comments in your new v09 patch.
Those are fixed OK now, but I found 2 new review points.
====
COMMENT trigger.c (typo)
+ ereport(ERROR,
+ (errcode(ERRCODE_DUPLICATE_OBJECT),
+ errmsg("trigger \"%s\" for relation \"%s\" is a constraint trigger",
+ stmt->trigname, RelationGetRelationName(rel)),
+ errhint("use CREATE OR REPLACE CONSTRAINT TRIGGER to replace a
costraint trigger")));
Typo in the errhint text.
"costraint" -> "constraint"
====
COMMENT create_trigger.sgmg (add more help?)
I noticed that the CREATE OR REPLACE FUNCTION help [1] describes the
OR REPLACE syntax ("Description" section) and also mentions some of
the restrictions when using REPLACE ("Notes" section).
[1] - https://www.postgresql.org/docs/current/sql-createfunction.html
~~
OTOH this trigger patch does not add anything much at all in the trigger help.
Shouldn't the "Description" at least say something like:
"CREATE OR REPLACE will either create a new trigger, or replace an
existing definition."
Shouldn't the "Notes" include information about restrictions when
using OR REPLACE
e.g. cannot replace triggers with triggers of a different kind
e.g. cannot replace triggers with pending events
What do you think?
