[9.4 CF 1] Patches which desperately need code review

Hackers,

The following three patches really really need some code review love.
Until they get a code review, we can't close out the CommitFest:

Row-Level Security:

Revive Line Type:
https://commitfest.postgresql.org/action/patch_view?id=1154

Performance Improvement by reducing WAL for Update Operation:
https://commitfest.postgresql.org/action/patch_view?id=984

Thanks!
