While I generally like the idea, please note that safe reading output
from queries is possible, with COPY, and proper IFS, like:
=$ psql -c "select * from t"a | b | c
----+-----+-----------a1 | b 2 | c|3a +| b +| c:| 64 | 5 +| | |
(2 rows)
=$ psql -qAtX -c "copy (select * from t) to stdout" | while IFS=$'\t' read -r a b c; do echo -e "a=[$a] b=[$b] c=[$c]";
done
a=[a1] b=[b 2] c=[c|3]
a=[a
4] b=[b
5
] c=[c:| 6]
that being said - I would love to get more functional psql.
Best regards,
