My guess is there is an index on the column:

    test=> create table txt (val text);
    CREATE TABLE
    test=> create index i_txt on txt(val);
    CREATE INDEX
    test=> insert into txt values (repeat('long string', 1000000));
    ERROR:  index row requires 125944 bytes, maximum size is 8191

You should probably not index long columns but rather index an md5 hash
of the value.
