Can I suggest to say:
"Limit bind parameter values reported by non-error statement-logging messages
to this many bytes". Or,
"The maximum length of bind parameter values to log with non-error
statement-logging messages".

Could you make zero a normal value and -1 the "special" value to disable
trimming ?
Setting to zero will avoid displaying parameters at all, setting to -1 wil
display values in full.
