gin_numeric_cmp() can be called from regular SQL. I missed this before,
but that function will segfault if you call gin_numeric_cmp(NULL, 1) (in
v0.7 at least).
I know you mean a C NULL, not a SQL NULL, but it reminded me to test SQL
NULL.
And how does GIN handle SQL NULL values in the column? Does it index
them at all, or just ignore them?
