Can't copy between 2 Postgres databases using COPY FROM DATABASE

[anikoo-aka]

What happens?

I have attached 2 Postgres databases (PG14 and PG15) and able to run queries on both databases. PG15 database is empty and does not have any tables. When I run the following statement, I get an error:

COPY FROM DATABASE pg14 TO  pg15;

Invalid Error: Failed to execute query "CREATE INDEX orders_pkey ON public.orders()": ERROR:  syntax error at or near ")"
LINE 1: CREATE INDEX orders_pkey ON public.orders()
                                                  ^

I tried to copy the schema only using the query below and got the same error:

COPY FROM DATABASE pg14 TO  pg15 (SCHEMA);

Have you tried this on the latest main branch?

• I agree

Have you tried the steps to reproduce? Do they include all relevant data and configuration? Does the issue you report still appear there?

• I agree

(I see a similar issue in #260 but that's related to postgres and this is mysql, my relevant code (on the latest version) works with postgres)

(for what it's worth "export database" works only "copy from database" works - I'm not blocked on this or anything I'm just trying to be a good OS citizen and report bugs as I run into them)
