Revision 10353

schemas/util.sql: map_nulls(): turned off STRICT to allow dynamic inlining, which causes a 2x speed improvement1. (see r10352 for an explanation of dynamic inlining.) note that turning off STRICT disables NULL-skipping (avoiding running a function when all its params are NULL), so it should only be used when the NULL-skipping optimization is needed less than dynamic inlining.

[1] the profiling query
SELECT util.map_nulls(array[v, 2, 3], v) FROM unnest(array_fill(1, array10000)) f (v)
has a runtime of 4157 ms with STRICT -> 2001 ms without = 2x speed improvement
