Hi,
Suppose, I have a table as below :-
id | title | content | tags
----+--------------+----------------+-------------------
1 | sample post | lorem ipsum | {apple,orange}
2 | another post | fruits are bad | {apple,hamburger}
3 | third post | foo bar | { banana, lemon }
4 | third post | foo baz | { watermelon, lemon }
Now I want to select all rows, for which tags will having either one
or all value from the this array [apple,banana] ? how should I write
the query using such a set ?
output should select 1,2,3.

Perhaps the && (overlaps) operator will work best for you. Check out the
available operators at:
