Why must an array have an even number of elements? I need to use a trigger function on any table, some of which may have an odd number of columns that I want to cleanse before inserting/updating.
The hstore function get parameters as sequence of pairs (key, value) - so the number should be even. Odd parameter signalize broken format.
Your example is pretty crazy - I cannot to decode it. Maybe you should to use different function, I don't see a sense for using hstore type there. But I cannot to decode it.

Is there a workaround for this?
ERROR: array must have even number of elements

-- code snippet that produced the error. -- new will be substituted for $1 during execution with using clause l_query_string := 'select ($1 #= hstore(array[' || l_column_list || '])).*'; execute format(l_query_string) using new into new; return new;
Thanks for your help!
