I have been looking at that, and it seems to me that you nailed it.
That's a nice improvement compared to the existing error handling with
multiple relkinds.
+ ereport(ERROR,
+ (errcode(ERRCODE_WRONG_OBJECT_TYPE),
+ errmsg("ALTER action %s cannot be performed on relation
\"%s\"",
+ action_str, RelationGetRelationName(rel)),
+ errdetail_relkind_not_supported(rel->rd_rel->relkind)));
Perhaps the result of alter_table_type_to_string() is worth a note for
translators?
+ case AT_DetachPartitionFinalize:
+ return "DETACH PARTITION FINALIZE";
To be exact, I think that this one should be "DETACH PARTITION
... FINALIZE".
+ if (relkind == RELKIND_INDEX || relkind == RELKIND_PARTITIONED_INDEX)
+ ereport(ERROR,
+ (errcode(ERRCODE_WRONG_OBJECT_TYPE),
+ errmsg("cannot change schema of index \"%s\"",
+ rv->relname),
+ errhint("Change the schema of the table instead.")));
+ else if (relkind == RELKIND_COMPOSITE_TYPE)
+ ereport(ERROR,
+ (errcode(ERRCODE_WRONG_OBJECT_TYPE),
+ errmsg("cannot change schema of composite type
\"%s\"",
+ rv->relname),
+ errhint("Use ALTER TYPE instead.")));
I would simplify this part by removing the errhint(), and use "cannot
change schema of relation .." as error string, with a dose of
errdetail_relkind_not_supported().
+ errmsg("relation \"%s\" cannot have triggers",
+ RelationGetRelationName(rel)),
Better as "cannot create/rename/remove triggers on relation \"%s\""
for the three code paths of trigger.c?
+ errmsg("relation \"%s\" cannot have rules",
[...]
+ errmsg("relation \"%s\" cannot have rules",
For rewriteDefine.c, this could be "cannot create/rename rules on
relation".
