Hi,

Coverity flagged a couple of issues that seem to worth addressing by
changing the code instead of ignoring them:

01) heap_xlog_update() looks to coverity as if it could trigger a NULL
pointer dereference. That's because it thinks that oldtup.t_data is
NULL if XLR_BKP_BLOCK(0) while reconstructing incremental
tuples. That fortunately can't happen as incremental updates are
only performed if the tuples are on the same page.
Add an Assert().
02) Be a bit more consistent in what type to use for a size
variable. Inconsequential, but more consistent.
03) Don't leak memory after connection aborts in pg_recvlogical.
04) Use a sensible parameter for memset() when randomizing memory in
reorderbuffer. Inconsequential.

Could somebody please pick these up?

I have to say, I am not particularly happy with the complexity of the
control flow in heap_xlog_update() :(.

Greetings,

Andres Freund
