I have been looking at a couple of simple patterns across the tree but
no luck here either. Well, if some

Yeah, I agree that the

So, the two code paths patched here are rather isolated. The one in
TransactionIdIsInProgress() requires an overflowed

Thanks for taking a look!

+1 for the proposal. I d
Hi hackers,
Now that we have some optimized linear search routines [0], I thought I'd
quickly check whether we could use them elsewhere. To start, I took
another look at a previously posted patch [1] and noticed two potentially
useful applications of pg_lfind32(). The attached patches replace th
