I downloaded gvim and viewed the file. It shows the filler field in position 61 as "^@", two characters, position 62 starts the next field.
I've tried the following:
COPY tblparcelto_tmp FROM '/pacelto.txt' WITH NULL AS '\^@'
COPY tblparcelto_tmp FROM '/pacelto.txt' WITH NULL AS '\^\@'
COPY tblparcelto_tmp FROM '/pacelto.txt' WITH NULL AS '^@'
...and many, many other combinations to try to get it to work. No matter what I try each record is truncated at position 60.
Shouldn't this work? I'm considering abandoning the WITH NULL attribute and use a line editor to take care of the problem. It just seems like this should work and there's something about the character set or NULL value that I don't understand.
Any suggestions would be appreciated.

My plan is to use a temporary table with one CHAR column to load the file, then use a second staging table to parse the fields and set appropriate data types. When I use the COPY command to load the temporary table I only get part of the record. When I encounter a FILLER column, which appears to be a NULL value, the rest of the record starting with the Filler doesn't load. Total record size is 455, at position 61 is the first filler field, defined as PIC X(1) from the legacy system. I'm able to load all the records in the file into the temporary table, but only for positions 1 through 60. When I looked at the flat file in TextPad, TextPad lists a special character at position 61 with a value as "NUL (^@ = 0 = 0x0)".
