Message-ID: <169590536647.3727336.11070254203649648453@wrigleys.postgresql.org> (raw)
The following documentation comment has been logged on the website:
Page: https://www.postgresql.org/docs/16/app-pgrestore.html
Description:
Good Morning,
In the `pg_restore` docs
(https://www.postgresql.org/docs/current/app-pgrestore.html), `--if-exists`
states that it is to
> Use conditional commands (i.e., add an IF EXISTS clause)
> to drop database objects. This option is not valid unless
> --clean is also specified.", but not being a SQL expert,
> I'm having a hard time deciphering this.
Suggestion: Would you consider adding the sentence (or something similar)?
> "--clean makes pg_restore drop all objects first,
> and --if-exists prevents that non-existent objects
> cause a failure."

This is succinct, and tells exactly what one needs to know. Thank you and
have a great day!
Appreciatively,
Attila
