While trying to fix a problem for David Fetter, I found this rather obscure plperl bug. It occurs, I think, in these 2 lines in plperl.c::plperl_get_elem():
if (hv_exists_ent(hash, eval_pv(key, TRUE), FALSE))
svp = hv_fetch(hash, key, strlen(key), FALSE);This works except where key is the name of a perl builtin function, when it comprehensively breaks, because instead of treating it as a string perl will return the value of the function from eval_pv(). I hope to have a solution soon, but meanwhile it needs to go on the open items list.
cheers

TIP 9: the planner will ignore your desire to choose an index scan if your
joining column's datatypes do not match
