RAISE statement not printing BIGINT? (hashids.encode_list)

[gpaterson]

In SELECT hashids.encode_list(
<p_numbers bigint[]>,
<p_salt text>,
<p_min_hash_length integer>,
<p_alphabet text>,
<p_zero_offset boolean>
)

Not sure if this is a POSTGRES error or what but when I run my code with a limit above 4 bytes on the integer array input I get an integer out of range error from line 48:

    raise notice '%[%]: % for %', p_numbers, v_i, v_number, v_count;

My code as follows:
sDateTime := to_char(NOW()::timestamp, 'YYYY-MM-DD HH24:MI:SS.MS');
RAISE NOTICE 'DateTime is: %', sDateTime;
iBigLimit := 92233720368547757;
sSalt := 'G Salt';
FOR i IN 1..length(sDateTime) LOOP
ch := SUBSTRING ( sDateTime ,i , 1 );
IF iBig < 1 THEN
iBig = ascii(ch);
ELSE
iBig := iBig*100 + ascii(ch);
END IF;
RAISE NOTICE 'ch is : %, %', ch, iBig;
IF iBig > iBigLimit THEN
iBigArr := array_append(iBigArr, iBig);
iBig := 0;
END IF;
END LOOP;
IF iBig > 0 THEN --Need to do this otherwise we miss the last digits
iBigArr := array_append(iBigArr, iBig);
END IF;

RAISE NOTICE 'iBigArr is: %', iBigArr;
sHash := hashids."encode_list"(iBigArr, sSalt,1);
RAISE NOTICE 'Hash is: %', sHash;

SQL output is:
