Well, I found that this problem was caused by selfuncs.c:gethilokey():
static ScanKeyData key[3] = {
{0, Anum_pg_statistic_starelid, F_OIDEQ},
{0, Anum_pg_statistic_staattnum, F_INT2EQ},
{0, Anum_pg_statistic_staop, F_OIDEQ}
: skankeys are hardcoded without call to ScanKeyEntryInitialize() =>
without initialization of sk_func.fn_oid required, I assume, by
new PL support code. Patch for this place follows...
One should check all places where ScanKeyData is used.
Jan, could you do this ?
(Oh, hell! I got this ERROR while testing subselect and spent so many time
to fix this problem...)
