Thread: pgsql: Attach FPI to the first record after full_page_writes isturned
Attach FPI to the first record after full_page_writes is turned on. XLogInsert fails to attach a required FPI to the first record after full_page_writes is turned on by the last checkpoint. This bug got introduced in 9.5 due to code rearrangement in commits 2c03216d83 and 2076db2aea. Fix it by ensuring that XLogInsertRecord performs a recomputation when the given record is generated with FPW as off but found that the flag has been turned on while actually inserting the record.
