Nathan Bossart 71ea0d6795 Restrict psql meta-commands in plain-text dumps. ... A malicious server could inject psql meta-commands into plain-text dump output (i.e., scripts created with pg_dump --format=plain, pg_dumpall, or pg_restore --file) that are run at restore time on the machine running psql. To fix, introduce a new "restricted" mode in psql that blocks all meta-commands (except for \unrestrict to exit the mode), and teach pg_dump, pg_dumpall, and pg_restore to use this mode in plain-text dumps. While at it, encourage users to only restore dumps generated from trusted servers or to inspect it beforehand, since restoring causes the destination to execute arbitrary code of the source superusers' choice. However, the client running the dump and restore needn't trust the source or destination superusers.
