Hello,

I noticed that pg_control_init() is failing an assertion on 13devel:

    TRAP: FailedAssertion("(atti->attalign) == 's'", File: "heaptuple.c", Line: 160)
    postgres: bossartn postgres [local] SELECT(ExceptionalCondition+0x55)[0x8e02b5]

The attached patch seems to clear this up.  I think this was missed in
2e4db241.
