CreateRole() was passing a Value node, not a RoleSpec node, for the newly-created role name when adding the role as a member of existing roles for the IN ROLE syntax. This mistake went unnoticed because the node in question is used only for error messages and is not accessed on non-error paths. In older pg versions (such as 9.5 where this was found), this results in an "unexpected node type" error in place of the real error. That node type check was removed at some point, after which the code would accidentally fail to fail on 64-bit platforms (on which accessing the Value node as if it were a RoleSpec would be mostly harmless) or give an "unexpected role type" error on 32-bit platforms. Fix the code to pass the correct node type, and add an lfirst_node assertion just in case. Per report on irc from user m1chelangelo. Backpatch all the way, because this error has been around for a long time. |
