Hello. Here are these functions with detailed documentation: http://en.dklab.ru/lib/dklab_postgresql_patch/
intagg.int_array_append_aggregate(int[]): fast merge arrays into one large list intarray._int_group_count_sort(int[], bool): frequency-based sorting intarray.bidx(int[], int): binary search in a sorted array Tested for about a year on a real PostgreSQL cluster (10 machines, Slony replication) under a heavy load (millions of requests). No crash nor memory problem detected during a year, so I suppose these functions are well-tested. What do you think about that?
