You can always have a text file (file.sql):

\pset ...
select .....


the run the commands is a single client connection with

psql database -Atf file.sql

This runs a file of sql commands in a single psql connection instead of
opening a new connection for every -c "" command.
Thus the result of the \pset is still in force when the next sql
statement is executed.

or run your command as it is & pipe the output through tr to translate
the commas to tabs.
You can see what tr does using
echo "1,2" | tr "," "\t"

eg:
psql $DATABASEHOST -U $DATABASEUSER -d $DATABASE -q -P footer -A -F , -c "$DETAIL_SQL" | tr "," "\t" >table.csv
