Here is a new function which could produce an array of numbers with a
controllable array length and duplicated elements in these arrays. I
used it when working with gin index, and I think it would be helpful for
others as well, so here it is.
select * from normal_rand_array(5, 10, 1.8::numeric, 3
It looks useful, for example, it can be used in sorting tests to make them more
interesting. I just have one question. Why are you using SRF_IS_FIRST CALL and
not _PG_init?
Best regards, Stepan Neretin.
