Re: clone_schema function - Mailing list pgsql-general
Igor,
I understand your point, however, I have spent over a week making a function
that previously did very little do a lot.
Naming a table the same as a schema is a very silly idea.I understand your point, however, I have spent over a week making a function

That is correct. But table old will NOT be converted to new because
only the schema name is converted. And table "old" WILL exist because it will also be copied.
I have tested and it works properly.
Please do not provide hypothetical examples. Give me an actual working example that causes the problem.
This statement:
SELECT old.field FROM old.old;
selects column “field” from table “old” which is in schema “old”.
Your script converts it into:
SELECT new.field FROM new.old
which will try to select column “field” from table “old” in schema “new”.
Again:
SELECT new.field
means select column “field” from table “new”, which does not exists.
Not sure, what other example you need.

Igor Neyman
