2018-12-07 13:47:48.047 UTC [63] ERROR:  22001: value too long for type
character varying(6)
2018-12-07 13:47:48.047 UTC [63] LOCATION:  varchar, varchar.c:624
2018-12-07 13:47:48.047 UTC [63] STATEMENT:  update visionet_berechnung set

even having set parameters
   log_statement=all
   log_error_verbosity=VERBOSE
the value for column with more than 6 characters is not shown.

In all other logged queries before there ware lines like
   DETAIL:  parameters: $1 = '13533', $2 = 't', $3 = '257', $4 = '28', $5 =
'1298'
and so on. But not  for the erroneous statement.

Hello

Yes, this is known limitation. We can not print parameters if query was terminated.
I would like to fix this, but have no idea on proper design.
