Postgres temp tables being are being created with column names larger than maximum

When running an insert on a table called yyyyy_yyyyyyyyyyyyy_yyyyyyy_yyyyyy with 2 fields called xxxxx_xxxxxxxxxxxxx_xxxxxxx_answer_id and xxxxx_xxxxxxxxxxxxx_xxxxxxx_id

Npgsql.Bulk will run the query:

CREATE TEMP TABLE _temp__a85e0e06_a254_4805_b172_28627fbcfd4d_54 ON COMMIT DROP AS
SELECT
    "yyyyy_yyyyyyyyyyyyy_yyyyyyy_yyyyyy"."xxxxx_xxxxxxxxxxxxx_xxxxxxx_answer_id" AS 
yyyyy_yyyyyyyyyyyyy_yyyyyyy_yyyyyy_xxxxx_xxxxxxxxxxxxx_xxxxxxx_answer_id,

    "yyyyy_yyyyyyyyyyyyy_yyyyyyy_yyyyyy"."xxxxx_xxxxxxxxxxxxx_xxxxxxx_id" AS 
yyyyy_yyyyyyyyyyyyy_yyyyyyy_yyyyyy_xxxxx_xxxxxxxxxxxxx_xxxxxxx_id
FROM
    "yyyyy_yyyyyyyyyyyyy_yyyyyyy_yyyyyy"
LIMIT
    0

However, postgres caps column names at 63 characters and discards all the characters after that limit, resulting in the error:

ERROR: column "yyyyy_yyyyyyyyyyyyy_yyyyyyy_yyyyyy_xxxxx_xxxxxxxxxxxxx_xxxxxxx_" specified more than once

Could some UUID be used instead of simply concatenating the table and column names?
