Currently bytea_output supports values of 'hex' (the default) and
'escape' (octal).  'hex' uses two characters per byte, while escape uses
three (ignoring the prefix overhead of \x or \[0-9].)

It is my understanding that base64 uses 1.37 characters per byte:

Is there a reason we don't support base64 as a bytea_output output
option, except that no one has implemented it?
