These characters prematurely terminate Windows shell command processing, causing the shell to execute a prefix of the intended command. The chief alternative to rejecting these characters was to bypass the Windows shell with CreateProcess(), but the ability to use such names has little value. Back-patch to 9.1 (all supported versions). This change formally revokes support for these characters in database names and roles names. Don't document this; the error message is self-explanatory, and too few users would benefit. A future major release may forbid creation of databases and roles so named. For now, check only at known weak points in pg_dumpall. Future commits will, without notice, reject affected names from other frontend programs. Also extend the restriction to pg_dumpall --dbname=CONNSTR arguments and --file arguments. Unlike the effects on role name arguments and database names, this does not reflect a broad policy change. A migration to CreateProcess() could lift these two restrictions. Reviewed by Peter Eisentraut. Security: CVE-2016-5424
