Can not insert a CSV with an array column

[iglesu]

It seems having the same delimiter for columns and the elements of the array confuses the Postgres copy command.
One solution I found was to set the delimiter to something else, e.g. | and leave the delimiter for the array to be comma separated.

A better solution is to simply quote the array:
E.g.
COPY mydb_3195.test_qm_import_fits (targetid,targetcode,fluxarray) FROM stdin CSV DELIMITER ',';
19722,ABCD,"{{24.82,5.42},{0.10,14.04}}"
75828,ABC,"{{514.06,60.03},{82.43,19.31}}"
