Обсуждение: pgsql: Refactor setting XLP_FIRST_IS_OVERWRITE_CONTRECORD.

Refactor setting XLP_FIRST_IS_OVERWRITE_CONTRECORD.

Set it directly in CreateOverwriteContrecordRecord(). That way,
AdvanceXLInsertBuffer() doesn't need the missingContrecPtr global
variable. This is in preparation for splitting xlog.c into multiple
files.
