datatype by array_eq and array_cmp; use this to solve problems with memory leaks in array indexing support. The parser's equality_oper and ordering_oper routines also use the cache. Change the operator search algorithms to look for appropriate btree or hash index opclasses, instead of assuming operators named '<' or '=' have the right semantics. (ORDER BY ASC/DESC now also look at opclasses, instead of assuming '<' and '>' are the right things.) Add several more index opclasses so that there is no regression in functionality for base datatypes. initdb forced due to catalog additions.
