Обсуждение: pg_restore --clean --create reference documentation incongruity

Hi,

I'm trying to restore a backup (of TEST2 db) into TEST1 db with the pg_restore options --clean –create.

This is the command launched:

pg_restore -v -h localhost -p 54321 -U postgres -d TEST1 -c -C -F c /Users/matt/Desktop/TEST2.backup

and this is the output:

pg_restore: connecting to database for restore

pg_restore: dropping DATABASE TEST2

pg_restore: creating DATABASE TEST2

pg_restore: connecting to new database "TEST2"

pg_restore: connecting to database "TEST2" as user "postgres"

pg_restore: creating SCHEMA public

pg_restore: [archiver (db)] Error while PROCESSING TOC:

WARNING: errors ignored on restore: 1

Now, now as described in the reference documentation

-C
--create

Create the database before restoring into it. If --clean is also specified, drop and recreate the target database before connecting to it.

When this option is used, the database named with -d is used only to issue the initial DROP DATABASE and CREATE DATABASE commands. All data is restored into the database name that appears in the archive.

I expected the specified db (-d TEST1) was dropped and created, not the TEST2 db.

In essence it seems that the –d parameter is ignored and TEST1 db remains untouched.

What is the correct behavior? Is a pg_restore error? Is a reference documentation error? Or simply I have not interpreted correctly it?

Thanks in advance,

matt

Ok, -d intended as the database to connect to, makes sense.
