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