Hi,
I've tried to create clustered index on table, pgAdmin generated SQL:
CREATE INDEX
ON "Calc"."tblDBObjectsDefs" (fullname ASC NULLS LAST);
ALTER TABLE "Calc"."tblDBObjectsDefs" CLUSTER ON ;
Problem is that I tried to create unnamed index, to allow DB to name it. Because of that, ALTER TABLE statement is not valid (no index name after CLUSTER ON).
My suggestion is to disallow create clustered indexes when there is no explicit name given by the user.
Regards,
Bartek
