`\i C:<path>/file.sql`

Can any one tell me please, how to get this db into server. Help appreciated. Thanks

Answer 1

In general, you can issue \\set ON_ERROR_STOP in psql before including a SQL file, to stop at the first error and not be flooded by subsequent errors.

When trying to copy into a non-existing table, COPY fails and all the data after it is rejected with a lot error messages.

Looking at the beginning of your dump, there seems to be a few problems indeed.

It creates a table named bensonsorderlystats_call but then gives ownership to postgres to another public.stats_call which is not supposed to exist.

And then it tries to COPY data into a table named stats which is also never created, assuming you're restoring into an empty database.

It looks as if someone manually edited the dump and messed up.

尝试使用psql -U username -f dump.sql database_name 。
