Hello, I wanted to ask according such a problem which we had faced with.
We are widely using postgres arrays like key-value array by doing like
this:
{{1,5},{2,6},{3,7}}
where 1,2,3 are keys, and 5,6,7 are values. In our pgSql functions we
are using self written array_input(array::numeric[],
Hello
do you know FOREACH IN ARRAY statement in 9.1
this significantly accelerate iteration over array
