Add nkeys parameter to recheck_matched_pk_tuple()
The function looped over ii_NumIndexKeyAttrs elements of the skeys
array, but one caller (ri_FastPathFlushArray) passes a one-element
array since it only handles single-column FKs. The function
signature did not communicate this constraint, which static analysis
flags as a potential out-of-bounds read.
Add an nkeys parameter and assert that it matches
ii_NumIndexKeyAttrs, then use it in the loop. The call sites
already know the key count.
