PFA a patch that rectifies this issue, by moving the XLogBeginInsert()
down to where 1.) we have all relevant buffers pinned and locked, and
2.) we're in a critical section, making that part of the code
consistent with the general scheme for XLog insertion.
In the same function, there is disorder of XLogBeginInsert and START_CRIT_SECTION.
```
collectordata = ptr = (char *) palloc(collector->sumsize);
data.ntuples = collector->ntuples;
if (needWal)
XLogBeginInsert();
START_CRIT_SECTION();
```
Shall we adjust that too?
