PLAIN password scheme issue with {}

Hello,

Using PLAIN password scheme and a user having a password with {} for example {RnDR8DaD} causes the authentication to fail:

auth-worker(85632): Error: conn unix:auth-worker (uid=143): auth-worker<3333>: sql(user@domain.com,123.45.68.78,<EBh0ouPWULvTF5AQ>): Unknown scheme RnDR8DaD

Is there some sort of a workaround for this other than requesting user not to use {} at beginning and end of their password?
