i have some sql functions written in c code using version 0 calling convention. it's working fine on postgresql 9.6, but i'm migrating to v13. has this calling convention been removed?
my function creation give an error,
SQL Error [42883]: ERROR: could not find function information for function "test_func"
Hint: SQL-callable functions need an accompanying PG_FUNCTION_INFO_V1(funcname).
